    @quasheezy,

    The reason you're not having any luck is that you haven't ripped the encryption first. You need to use something like DVD Decrypter OR AnyDVD to decrypt the movie THEN you can use CloneDVD2 and Nero.


    actually decrypter is what i use to rip my movies to my hard drive. i've only been making backups for about a year now, but decrypter is the one program that has never given me any problems!

    i unistalled roxio like you suggested, and used the zapper to clear the registry. i unistalled nero(with all the necessary tools and restarts) and reinstalled, but i'm still not having the best luck with shrink. it works fine, it just takes a little too long for my tastes. i have an hdtv and a pretty nice dvd player or whatever, so quality is something i most certainly am concerned with. shrink is a great program, but it takes about 3 hours to compress a movie down to burnable size, 5 if i use deep analysis.

    i'm absolutely certain that it's my system's limitations that are suffocating shrink, so i'll most definitely take your advice about the msconfig and ram upgrade.

    However, I do have a question about shrink that you may be able to help with. Say I've already ripped a 7 gig movie to my hard drive using decrypter and I want to burn it to a dvd 5 using shrink. [bold]can shrink burn it directly to the dvd without first compressing it in a backup folder?[/bold] i think that would be an instrumental part of speeding up the process. i ask this because that is what the roxio program i used did. the max it would take depending on the amount of compression necessary, was about 15 minutes and quality was excellent. however, about 85% of the people i've come across in dvd forums will say that roxio was a program created by the devil himself. and when this many people agree, there's certainly some truth to it. i guess i was just one of the few it worked well for.

    oh well, i'll be building a new pc soon, so hopefully shrink will work a bit quicker on that one.

    Check your DMA settings - How ? do this -> Go to Control Panel> System> Hardware Tab> Device Manager> IDE ATA/ATAPI controllers> Right Click Primary IDE channel (and Secondary IDE channel after you finish with Primary)> Properties> Advanced Settings Tab> Transfer Mode or you can go here for another guide http://club.cdfreaks.com/showthread.php?t=101616

    Do the above from both "Primary & Secondary IDE channels".

    I (We) and you need to look at whats in both "Transfer Mode" and "Current Transfer Mode". Screen shot below is what I'm talking about.

    You can also look here for some other solutions: http://sniptools.com/vault/getting-back-to-dma-mode-in-windows-xp.htm

    If it is in "PIO" mode. Click the "Driver" tab, and uninstall the driver. Then reboot. Upon rebooting windows will automatically reinstall the driver and it should go back to "DMA" mode.

    Even though Windows is reporting DMA is on, did you check the bios to see if it was on?

    Do you have your hard disk (hard drive) and the burner/reader on the same IDE channel?

    " Do you have your hard disk (hard drive) and the burner/reader on the same IDE channel?"

    that's an interesting question. it just so happens that i frequently switch hard drives in and out of my pc and i recently had to replace the ide cable to my hard disks. but i'm not exactly sure what you mean by same ide channel. also, i'm not sure how to check the bios.

    i talked to 3 more people who use shrink on the regular and they said that it takes 2-3 hours to enocde. is this the norm then? how long do you think it should take to just encode(not burn)?

    i appreciate everyone's willingness to help me. as long as the suggestions keep comimg, i'll keep doing them!

    Hi everyone...I really enjoy all of the very useful information I can pull out of these forums, but there is a problem I am unable to find an answer to...I am using shrink, 16x DL Memorex burner. The problem is with kung fu hustle...I'm getting a CRC @ 9% encoding. The disk is brand new...no scratches at all, I also tried cleaning it anyway but that didn't help. So if you could, please find it in your heart to rid me of this headache!!!!
    Thx.

    Almost all people have 1 "Primary" IDE channel and 1 "Secondary" IDE channel. Your "Hard drives" should be on the "Primary" IDE channel and your DVD-ROM and/or DVD burner/writer should be on your "Secondary" channel. It will run alot slower if the "Hard Drive" and "DVD-ROM/Burner" are on the same IDE channel. Also, when you replaced the "IDE Cable", did you replace it with a "40 Pin" IDE cable or a "80 Pin" IDE cable? If you used a "40 Pin", that could also be a reason why its going slow.

    Depends on if you are using the "Deep Analysis" feature of DVD Shrink and/or the "AEC" functions. I personally rip the entire DVD structure to my hard drive first, then open up the files through DVD Shrink. Your hard drive works much faster than your DVD-ROM/DVD burner when "reading" the data. Here is a guide I made that is step by step: http://forum.digital-digest.com/showthread.php?s=&threadid=45238

    On the average, I can rip a "Dual Layer" DVD in 15 to 17 minutes. Then encode/shrink with DVD Shrink in about 45 min (I do a "Deep Analysis" on everyone of my backups and I use the AEC function.) For single layer DVD, I don't even use DVD Shrink. I just do a "ISO Read" then a "ISO Write" with DVD Decrypter 3.5.4.0 to make a 1:1 identical copy.

    caP2 - RIP the DVD with DVD Decrypter 3.5.4.0 first.

    Make sure you have the latest version of DVD Decrypter.

    The latest Version is Currently: Version 3.5.4.0


    Use DVD Decrypter to "rip" the DVD to your hard drive in "File" mode - and from the "Edit" dropdown menu, select "All files" (NOT "movie files").

    Then use DVD Shrink to "Open files" (NOT "Open Disk") - and select "VIDEO_TS.IFO" or the actual "VIDEO_TS" folder.

    A good tutorial on how to accomplish this is located here: http://forum.digital-digest.com/showthread.php?s=&threadid=45238

    ScubaSteve…
    Ok I’m new to this site but I’ve read most of in and out and I found someone had a problem similar to mine but you wouldn’t answer because he didn’t give you proper information. That was on page one.

    I’ve tried with every program I’ve seen you suggest and wasted a lot of time on this silly DVD, I’ve used DVD Shrink, Clone DVD, Nero, DVD Decrypter, and CD Check to try and recover lost data.

    I’m trying to burn a season of a DVD 13 episodes and it gives out on 13% every time in every program, in Shrink I got the CRC error but in DVD Decrypter its listed as a “Failed to read sector, Un recovered Read Error”

    I’m trying to copy this data from a burn DVD, I believe it’s a bad burn, is there programs out there or other suggestions to recover this data? I’ve successfully burned DVDs from Season 1,2,4 and 5 so I know that the burned DVDs I got work, just I think this one may have had a error during burning. Thanks….

    Hello,
    I've been using the DVDShrink, DVDDecrypter duette to backup DVDs for over a year now (okay, actually I also involve ImgTool Classic to make an ISO image before burning with Decrypter. I usually copy and shrink the DVD to my Hard Drive directly with Shrink). Sometimes DVD Shrink encounters a CRC problem and closes, so then I use Decrypter instead to get the DVD on my HD and then open it from there with Shrink. I use the option "Ignore Read Errors" in Decrypter, and it works fine. Usually there are only a few CRC errors - once it gets past them, DVD Decrypter carries on decrypting normally. However, I am currently trying to backup an original DVD (Leon), and not only are there CRC errors on (only) one of the VOB files, but there seem to be loads of them. DVD Decrypter slows down to a turtle-speed while dealing with and "ignoring" the errors, and I even though I let it run all night, it only advanced 2 percent in that time, and had encountered over 7400 errors. I got tired and switched it off. Can anyone tell me (ScubaPete or jmet to the rescue?) what DVD Decrypter does by "ignoring" an error - does it or does it not copy the (corrupted) data anyway? Even if the cyclic check does not match, is the data played on a standard DVD player? The movie works fine on my JVC DVD player - no hint of any errors. I wonder if I should let DVD Decrypter carry on its work - it had reached 71% of the VOB file when the errors started, and by morning it was at 73%. At that rate it will take forever (unless the errors stop). If the remaining 30 % is full of errors, and DVD Decrypter ignores them all, is that data still readable in a standard DVD player? IS it worth waiting all that while (days, maybe weeks - can my PC handle the heat?) In short, a plea for HELP from your friendly Bee who knows more about making honey than computers. Thanks, yours truly, Bobbie the Bee.

    Bee, clean the disc and try it again. Even if it doesn't look dirty. Sometimes you have to hold the disc in different light at different angles to see the scratches, etc.

    Make sure you have the latest version of DVD Decrypter.

    The latest Version is Currently: Version 3.5.4.0


    Use DVD Decrypter to "rip" the DVD to your hard drive in "File" mode - and from the "Edit" dropdown menu, select "All files" (NOT "movie files").

    Then use DVD Shrink to "Open files" (NOT "Open Disk") - and select "VIDEO_TS.IFO" or the actual "VIDEO_TS" folder.

    But, you say "I am able to watch the DVD fine in my DVD player." That is irrelvant, as drives and players operate on different programming. Drives are logical, players can interpret digital signals and are not choked by bad data.

    jmet, thanks for your help. However, I have already:
    -cleant the disk
    -downloaded the latest version of DVD Decrypter
    -tried the disk on both my DVD drives
    -tried decrypting both in File Mode and ISO mode in DVD Decrypter
    I think DVD Decrypter is managing to get the DVD onto my Hard Drive, but the problem is it is taking far too long (probably too many errors). A question: when in the past I haven't been able to copy the DVD to my HD directly with DVD Shrink because of a CRC error, I have managed to do it with DVD Decrypter by "ignoring the errors". Does that mean that DVD Decrypter copies the data to the HD regardless of the CRC errors? And if so, why is DVD Shrink then able to open it once it is on the HD? Wouldn't it have those same errors even though I have managed to get it onto the HD? Sorry for these questions, but I am quite intrigued, and you seem to know so much (how do learn all these things?). Anyway, thanks again for your help,
    your friendly Bee

    If you have already cleaned the disc, tried it in different drives, and tried with DVD Decrypter and still get a CRC error message (Its a I/O error message usually in DVD Decrypter). I would say that disc is damaged enough to be "unrippable". Only solution to that would be to obtain a different copy that isn't messed up. That particular DVD if I researched it correctly, came out 5 years ago so it contains no newer copyright protection on it. Most defiantly it is damaged or it could be a "bad pressing" (Just like "Spanglish").

    Even though DVD Decrypter says it will take a long time to finish, in all actuality it will not finish but, eventually give you a I/O Error message after so many failed attempts to "Ignore" and/or "Retry" read errors.

    One of the advantages in using the DVD Decrypter & DVD Shrink combination is that, after it is ripped to the hard drive. You are done with the actual reading from the "disc". That is why DVD Shrink can open it. Setting DVD Decrypter to "Ignore" read errors, is not %100 fool proof. It copies what it can (therefore skipping the bad data). Sometimes even though you successfully ripped a DVD, you will still get a error message about the a file(s) missed in DVD Shrink cause DVD Decrypter "Ignored" that file and "Skipped" it like you told it to. In some instances it just so happens to be a file that you may or may not need to successfully open it up in DVD Shrink.

    My knowledge I have gained about this has come over the year from helping people just like you and experiencing the same problem myself. :)

    As jnet mentioned, it does sound like a "dodgy" disc.

    Before throwing in the towel on it, I would run it through CDCheck to sea if the errors on the disc can be rescued.

    Get the proggy here:

    as always, let us know how you make out -

    Hey now,
    it´s me again! Thanks for your advice, jmet: it´s a good thing I didn´t carry on trying to copy the disk to my HD with DVD-Decrypter, it would have taken many, many hours, even if it would have succeeded at all, which, as you said, is doubtful. I searched a bit on the net and came across another freeware proggy called DVD Fab Decrypter - I had to rip the whole disk again, but when it reached the bad VOB file, it just slowed down for a few MINUTES (though it was clearly advancing) and then picked up again to finish at the normal pace. I´m not sure what it did - whether it ignored the errors and simply skipped them, or copied the bad sectors per se (the file size was no different than the original, if you can go by that). Anyhow, DVD Shrink was then able to take over as usual, but reading from the Hard Drive, which makes me think that the bad sectors were skipped. Though I don´t understand the internal workings, I managed to backup the DVD just fine, so if you hadn´t heard of it, here is a new tool for our collection - just in case. It worked for me! And thank you also to Mr Scuba Pete, who seems to like always having his finger in the pie - which is fine, because it is a very helpful finger indeed. I checked out CDCheck, which looks like a handy tool - it confirmed the errors on my DVD Disk. Thanx for your help, guys - if there is anything I can help you with (I speak Spanish, some French, and am learning Italian)lemme know!
