Hi guys interesting stuff here - I posted the following in another forum before I found this post, so I'm gonna repeat it here:- Does anyone know what hardware mods may reduce the time shrink takes to back up DVDs with big compression? It doesn't appear to be related to processor speed on my comp because I have done a quick experiment involving the clock on my processor:- I shrunk 8mile DVD with shrink 3.1.4 with my processor running at stock speed (AMD xp2500 1.83Ghz - 166 FSB x 11) and it took 47 minutes 11 seconds I then deleted the files, changed my CPU speed to 2.14 Ghz (178 FSB x 12) and ran shrink on 8mile and again it took 47 minutes 11 seconds So anyone know what's the main control over copying speed? Is it my DVD drive? I use Pioneer 106 burner(latest firmware) to read and burn. Would buying a faster DVD rom drive to read help? I have checked the DMA settings and no problems there, I copied w/o burning to Nero and w/o Deep analysis
Think about it this way... If your SOURCE files are on DVD, then the rip speed is a factor. If your SOURCE files are on Hard-Drive, then IDE I/O is a factor. The fact that an increase in CPU speed (and probably memory speed as a consequence) made NO difference is strong indication that the process you are using is I/O bound (the movement of data from one medium to another is the bottleneck). Test this: REDUCE the speed of the CPU in large steps UNTIL the test shows an increase in processing time - that is the point at which CPU/Memory becomes the bottleneck. More info on your exact test procedure/environment is needed before an accurate recommendation can be made. Have Fun...
Ok, I think I've sussed it now I found a 3 year old sony DVD Rom drive lying around, slotted this in and ran shrink (ripping from DVD), the rate was much higher 3.7 Kb/s as opposed to 2.7 Kb/s with the A06, so I think the drive speed is the answer. Back up time is now down to 40 minutes on 8mile, so if I buy a pioneer ROM drive it should be even better! Thanks for help Drchips, I'll try dropping CPU settings to fing the processor speed bottleneck and post it for information, if I find it
Heres my results for 8 mile backup Decrypted the entire disc to hardrive in 8 mins Backed up the entire disc with shrink and deep analysis took 25 mins to analyse back it up and burn it, perfect backup
hi there, with a 2.5 Ghz barton core processor and 400 Mhz memory I rip my movies from an LG combo onto hard disk in 8-15 minutes or max 25 min with deep analysis. its also true that my pioneer 105 is slower at reading than my LG. i was tought that setting up your hardware configuration is also very important. If you have 2 dvd drives they should be on the secondary IDE channel with the writer set to slave and your hard drive and the primary IDE channel. Also the memory sticks if not placed correctly can really slow down your system. I experienced that some discs either have reading limitation. Incredible but copying on the fly the movie "back to the future" I've achieved 4.6X writing speed. Once again DVD Shrink is the best I've ever tried. all the best!
I rip all my movies with my lg dvd rom, with rpc-1 firmware i get roughly 9 to 10 x rip speed constant thanx to dr chips who gave me some good advice in these forums
Yeah, ditto, i too use my lg dvd rom for ripping and my pioneer a06 for burning, i get about 8.5-9.5MB/sec transfer, if uncompressed in about 14 minutes max. Compressing it usually doubles the time, @30% w/out deep analysis it takes about 25 minutes max, but i don't compress the movies overly much or at all with shrink, maybe a 10% compress at most, even tho people tell me dvd decryptor etc are better for smaller compressions, use shrink for big compressions.

HI guys, About the long times with DVDshrink. Just read that there is a slight problem between the new DVDshrink and Nero when the auto burn feature is used. They think the problem is with Nero and they are suppose to fix it in the next Nero update. They suggest un-checking the Auto burn box until the problem is fixed. Just thought I'd pass that on. It should help the slower systems work faster. Jerry
I was wondering about the encoding times times like the rest of you. It takes me over an hour to rip a DVD using a 16x DVD Rom. I'm running a P4 2.7 533fsb with a gig of DDR 333 mhz memory. 2 hours for a movie to rip and burn is about average for me. this is with shrink 3.1 when using Decrpypter the ripping time is about 20-30 minutes. When I use shrink 3.1 I also use the authoring settings so I'm not compressing the movie. Just burning the movie and leaving the nonsense out. Any thoughts to this? Thanks folks
Hi guys, just because your dvd rom says its a 16X doesn't mean you are getting that speed. Check your rip speed with dvdinfopro or Nero speed check. My burner says it is a 16x reader. Howerver rip speed was locked at 2x by the firmware. It took 1.5 to 2 hrs for a complete backup. I re-flashed the firmware, now I get 15-20 minute rip and 30-45 burn on 2x media. Processor is only a 1.3 gig. Jerry
the DMA is on, as for firmware, where would I find that out. It's a no name DVD Rom that came with the computer, I haven't found any new drivers?
Download this little program. It will tell lots of good information about your drive, and about and media you put in to it. http://www.dvdinfopro.com/ It will show who made your drive and firmware version. Jerry
