I've read several posts about this problem and am experiencing it myself. I've tried all the solutions and nothing works. Here is the problem I'm having and what I've tried. When ripping, Alien, Aliens, Terminator 3, and The Matrix Reloaded, at some point the both drives stop being able to read the disk. One drive is a Ricoh 5240a and the other drive is a Creative PC-DVD 6x. They both stop in the same places on each of these disks. I've tried opening the DVD's in PowerDVD first and pausing the movie to keep the files unlocked. This doesn't work. I've checked the disks for damage. There is no visible damage. I've installed new flash on the drives. Reinstalled drivers. Installed different ASPI drivers and so on. I even thought that my XP might be screwed up and did a clean install of XP (it was time for a clean install anyway). Nothing I have done works. I have others disks that will rip just fine. Transformers (all seasons), Gladiator, Lord of the Rings, and so on. I don't understand why these disks would be any different. If you have any ideas on how to fix this please let me know.
