    How long does crappy CMC -R media last before freezing & pixxilation problems show up in playback?

    I bought some shrinkwrapped Southern Gospel TV shows on Ebay that were made by Daystar TV but it's not the Daystar Network. They were recorded in May through August 2006 on an unknown duplicator & unknown speed. No I didn't pay very much for them only around $15. The guy that sold them is not part of the Daystar company.

    One disc had freezing problems in a standalone DVD-VCR player. I haven't tried playing them in my DVD (only) player or either one of my computers yet. What I plan to do after I watch all of the DVD's is rip them with decrypter then burn them on 8x TY media using Imgburn so when the CMC media goes bad (worse than it is) I'll have a backup I can play.

    Well the computer is playing the same disc flawlessly (on a Plextor 716-A drive) that froze up several times on the DVD-VCR player I first played it on. I guess it doesn't like this crappy media...

    Don't worry, I'll copy them to some 8x TY media in a day or two.

    Yes I know (for quite awhile) that CMC media is really crap (only thing worse is Princo) & I'd never buy or burn anything to either media. No way!!

    If the initial recording was good--low jitter, low parity errors--then the CMC discs should last at least 15 years. If the recording was on a drive not tuned well for the discs, then the discs will not last as long. The same is true for Taiyo Yuden or any other disc, but TY is generally compatible with most drives because of patent issues with optical recording. An exception is TY DVD+R 16X which was late to market and is less well supported. That means that "TY is really crap" if one judges quality by compatibility--an incorrect method of determining quality.

    I agree with JoeRyan. CMC media may be ok with some burners,not so for others. Hopefully those ebay discs were burned with a quality burner and not too fast.

    Main thing to watch for: Make sure you can rip them onto your harddrive without getting a CRC error. Especially that 1st disc that froze early on your stand alone player.

    Rip using dvd decrypter's ISO read mode. Burn the MDS files using ImgBurn. A very effective backup process for properly sized dvd-5 to dvd-5 backups.Pretty quick too!!!

    Any problems,post back. There's a couple default settings you can adjust to help you rip them in case of crc errors.

    BTW: Are there any sticker labels slapped on them?

    Labels are printed on each white surfave. Thanks for the info. I was going to back up these really good content (the shows were great!) on TY media using Decrytor/Imgburn anyway. Will post if I have a problem.....

    Actually, CMC media is quite good, IF, I repeat, IF, it's purchased under quality name-brands like HP.

    Well they all ripped to the HD (with Decrypter) & ImgBurn make the backup on TY media That way if the CMC media goes bad one day I'll still have the shows on TY discs.

    I just heard last night-slysoft forum- that cmagnetics and prodisc make verbatim media. By looking at the top clear part of the spindle for the letters Lock,with arrow for Open,that tells you if you got the prodisc or cmag verbatim. Supposedly the cmag verbatim have an Itallic look on the lettering,and the prodisc verbs will have ligit text for the lettering.


    They may make verbatim media,but they still use the advanced metal azo dye and the tight specifications of Mitsubishi Chemical Corp.

    I got that info from a post by Digital Dolphin who tests/burns dvd media for a living.

    There is alot of BS spoken about CMC on this list. CMC may of had some bad dvd media in the past, however CMC MAG.AE1 (8x-R) discs sold under good brands (ie LG, Imation and HP) are quite good. They use a AZO dye, and are not prone to degradation as are G05 and princo.
    I have personally used about 300 of them under the LG brand and have not had a bad burn yet. Noone has had any problem with them not working in their stand alone players. TRT and Kprobes results show good burns.
    I have had more problems using value lines TYG01's than these LG branded discs. Now I have a large blank dvd collection that numbers over 2000, including TYG01, G02, T02, MXL, MCC, LGE, CMC, Sony, TDK etc. so I have no reason to defend CMC if they were crap. I have other options.

    If you spent time over on CDFreaks, you would have known this years ago. Old news. There are hundreds of people there who know as much if not more than Digital Dolphin or DocTY. That's not what we're talking about here anyway. This is about CMC media with CMC media codes (Verbatim is a different issue altogether). A lot of people here trash CMC media across the board, but that's only because they are ignorant, and don't really understand media quality.

    Once again, under reputable brands like HP, CMC tends to be decent media. Period. No, it's not as good as Verbatim or TY, but it's definitely not the worthless crap that people always make it out to be. I wish the slander against CMC's reputation would just stop. It really gets to be tired and boring after awhile.

    Negritude: I'm sorry that I don't spend my whole life on the net and visit every forum site that has anything dealing with dvd media. I do have a life.

    Sounds like someone's pimping cmags on us!!!!

    You can have your cmags,while I get my Verbs,Tys,Hitachi,Ritek,and ricohs for the same price, and even cheaper than HP media-PERIOD!.

    My only point is twofold:

    1. DocTY is NOT a god.

    2. CMC is not THAT bad.

    That's it.

    3months away from the net/endless CMC debates, and i got hit by some CMC badness again. One of my standalone players went screwy with some TV shows on CMC's (16x +R with MID code of CMC MAG-M01). Major pixellation & skipping on some scenes. Though for a change i was able to get the data off most of the discs without effort (however 1 disc gave me severe grief on numerous drives, but got the data off eventually; unfortunately it'll be a while 'til i'm able to watch the episodes on the backup of that particular disc so don't know if my recopying attempts were completely successful). Good news is that the discs/episodes that initially went screwy seem ok on the new discs.
    No prizes for guessing what discs i picked for recopying onto...

    So.. back to TY of various sorts and speeds, and to prove i don't just push TY discs, i also get very good results with Maxell 16x +R (MID code of RICOHJPNR03), very cheap too, £16 for 100..

    I have very little time for forums these days, so need discs to 'just work, and keep working' even more than i usually would, time wasted faffing about with discs that 'might' or 'should' work is time i can't get back...

    WOW!! Where did that come from? I don't think anyone believes that docTY has attained deity status. He's a knowledgeable guy and has pertinent input when it comes to media especially TY media but bashing a member that has attained rightful AD ADDICT status is uncalled for in my book. I think that your comment was over the top and provocative at best.

    I don't know Digital Dolphin but I do know docTY and as far as I know he hasn't "bashed" CMC-MAG in quite a while. I really wouldn't call it bashing when the media at that time was definitely inferior to other available media, whether that media choice is TY, Verbatim, Ritek, Ricoh, Maxell (MXL coded) or any other reputable media.

    I can attest that the CMC-MAG stuff I've recently received for free from my so-called friends is less than desirable. I will include a few scans for perusal and let you decide for yourself. :p


    Recorded on a Philips external (sorry that's all I know a friend loaned me this) Scanned on a BenQ. Maxell DVD+R 16X
    [​IMG]
    Same disc scanned with a Litey for fairness. Maxell DVD+R 16X
    [​IMG]

    Another CMC-MAG with less than desirable results.......Memorex DVD+R 16X
    [​IMG]
    Same image but ripped from the disc above and then burned to a TYG03. I think there may be some differences, can anyone see them? lol.
    [​IMG]
    Another TYG03 with transferred data from a CMC-MAG (Memorex DVD+R 16X). I don't have the CMC-MAG handy right now but I'm sure the results would be similar to the other CMC-MAG's I've posted.
    [​IMG]

    Also for fairness I picked out "reputable" name brands with the CMC-MAG identifier. Maxell DVD+R and Memorex DVD+R, both 16X media. The ID codes are easily seen on the scans so there's no questions there. :p

    I'm not saying that CMC-MAG is crap but the ones that I've received lately are "bad" by definition. PIE's over 200 and PIF's over 4 (max's 7 & 61) from a Litey. I don't know how long they will last or if the drive that burned them was "well tuned" or not but they show to be of low quality and I would and have backed them up to KNOWN reputable media.

    @Negritude I hope that some light was shed on the subject of CMC-MAG's, at least the ones that I have. Maybe the AE1 CMC-MAG's are better than the M01's but at this point unless they have a long standing improvement I WILL NOT USE them purposefully for anything of importance.

    - indeed, a few unnecessary (and completely irrelevant) comments stand out in this thread; i've hardly looked at any threads the whole time i've been away, but it seems a few chips on shoulders are still rife here. Nothing like a bit of CMC media for that.

    And for a certain poster's info, i do follow loads of threads at cdfreaks, i just get increasingly put off with their obsession with quality scanning

    @greensman - i didn't realise CMC did Maxell 16x +R, the only Maxell 16x +R i buy are specifically RICOHJPNR03.

    edit- yup, seems there's a couple others too - http://www.videohelp.com/dvdmedia.p...rder=Name&hits=50&search=Search+or+List+Media

    I'll keep buying the Maxell's as long as www.svp.co.uk guarantee they're just the RICOHJPNR03's ie http://svp.co.uk/products-solo.php?pid=2004

    greensman: Those are the Maxell cmags that you got. I got the same results with my Maxell cmags. I won't get them again.

    Negritude stated they must be HP cmags or the other great cmags, LMAO!!!! We just gotta look for the awesome quality Cmags instead of the crappy Cmags.

    @creaky,
    Nice to see you back buddy. Hopefully your holiday was good and relaxing. ;-)

    Yep the Maxell CMC-MAG's (M01) are less than desirable and fortunately I didn't buy any a friend gave me a few. Yuck!!!!

    @Saugmon,
    Oh!! They are pretty bad. I have a few left but I've found that burning them at 4X helps a little. Like you said I won't get any again or in my case take 'em for free any more. LOL. That's sad when you can't even except something for free. hehehe.

    I just picked up a 100 pk spindle of sonyD21 at staple's for $25. I'll burn them and score 95+ on every one of them!!! I forgot an old HP empty ink cart to return or I could have had them for $22

    greensman,those scans in the 70's rate up there with Fuji Prodisc R05-001,so beware of the +16x MIT fuji.
