I have backed up a movie using DVDShrink (removing protections) and made a DVDR copy using Nero 7.x. It works fine in a DVD Player and plays with Nero Showtime, however when I went to copy the files back to my computer to make another copy I get read errors (cannot copy VTS_01_1.vob:cyclic redundancy check). This happens using Windows Explorer, DVDShrink, DVDFab, DVDDecrypt etc and on 2 different computers/drives. There is no copyright protection on the disc and the disc is clean with no marks. When I run the disc through Nero CD/DVD Speed surface scan, it shows alot (15%) bad. The media is Memorex (I have read the forums on media types and will heed the advice in the future and use TY media) and the burn was made only 1 month ago and hasn't been watched more than once. I also get this on more than 1 DVDR backup. I suspect now that it is the media, but how can it be playable with no errors, yet I cannot copy it to my hd?? Also I've read to shrink down to 4.2gb instead of 4.7gb to avoid burning near the edges of the disc where the dye may be inconsistent. Any thoughts?
