I'd been using DVD Decrypter for years and switched to ImgBurn a few months ago. Everything was running smoothly until this morning - the DVD is taking well over 90 minutes to decrypt (30 is typical) and the total time remaining is constantly changing. When the process begins it will show 18 minutes, increase to as much as 45 hours and run anywhere in between. I've checked to make sure that DMA is enabled, even going as far as uninstalling and reinstalling the IDE/ATA Controller. Nothing on my system has changed since using the program about 5 days ago. I'd appreciate any help you can offer.
