kallend 2,196 #1 February 16, 2005 I have a Nationals 2002 DVD that has developed a CRC error when I try to play it on my PCs (all of them, 4 different drives all with the same problem so I'm sure it's the disk). OTOH, my home DVD player seems to ignore the error and keep going, playing it just fine. Short of recording (analog output) from the DVD player to tape and capturing and burning an all-new DVD, is there any way to extract the files on the PC, ignoring the sectors (or whatever storage units they are) that have the CRC errors?... The only sure way to survive a canopy collision is not to have one. Quote Share this post Link to post Share on other sites
Synapse 0 #2 February 16, 2005 You could give DVD Shrink a try. Its a tool used to extract and shrink all of the data on a DVD disk for the purpose of backing it up/copying it. If the data on the disk isn't over 4.7GB then it won't perform any unnecessary compression on the video. Once you have the .VOB files extracted from the disk you can use any DVD burning software (nero) to make a new disk. DVD Shrink doesn't have the option to "ignore CRC errors", but it is most likely to be a little less picky about that than the software you are trying to view the disk with. If that doesn't work though, you could probably use something like nero to do a DVD to DVD copy of the disk and I'm pretty sure that you can specify that you want it to ignore CRC errors. The disk would have to be copyright protection free though since Nero won't copy it otherwise. Hence the need for DVD Shrink. I'm not positive on the nero CRC stuff though and I'm not at home where I can check. *shrug* Its worth a try. One of those disk scratch removal kits may not be a bad idea either. -synThey who can give up essential liberty to obtain a little temporary safety, deserve neither liberty nor safety. - Benjamin Franklin Quote Share this post Link to post Share on other sites

I'll give Nero a try tonight and see if that works. Thanks.... The only sure way to survive a canopy collision is not to have one. Quote Share this post Link to post Share on other sites
Synapse 0 #4 February 17, 2005 No problem man. Let me know if you still can't get it to work, I know I've got to have some application around here that will ignore the errors. If the DVD player can read it, then by god so should the computer! -synThey who can give up essential liberty to obtain a little temporary safety, deserve neither liberty nor safety. - Benjamin Franklin Quote Share this post Link to post Share on other sites
kelpdiver 2 #5 February 17, 2005 what happens when you simply try to copy the dvd files onto the hard drive? If you can get it to ignore the error, might end up with just a bad glitch where the bad spot was. There's no need to use dvd shrink or dvd decryptor for an unprotected disc with this problem. Next stop would be dvdrhelp.com - lots of utilities there. Quote Share this post Link to post Share on other sites
op5e 0 #6 February 17, 2005 Normally a good clean will fix these problems. Look at the label side to see if there are not scratches or blisters. Pay special attention to the inside circle. DVD diagnositics is a great program that has recovered alot of things for me in the past. But it costs money and of course at the end of the day it could be a phsyical fault with the disc, and recovering 99% of the data might mean you still can't view your video. Most of the time I just give my discs a very good clean. Remember to polish ONLY the side opposite to the label. When polishing do it from the centre to the outside. It must be mirror finish else the scratches may still affect the disc. Polishing compounds sometimes help, but its normally easier to get a CD polishing kit. http://www.infinadyne.com/cddvd_diagnostic.html Also there might be the fact that its a (say) DVD-R disc and you are putting it in a DVD+R player or visa versa. This happened to me recently and only the newer multi readers would read a disc. In this case I just used DVD shrink to copy the dvd (from a drive that it worked on) to a DVD format that I knew worked. Quote Share this post Link to post Share on other sites
