Thanks, Jaminsd. I always use DVD-Rs, and use "One Click DVD Copy 4.2" to copy. I have "Power DVD" , but it doesn't want to play some of them. Thinking it might be the disks I was using, I tried other disks, but that didn't change a thing. I think it's (either the program or the drive) just balking at playing something that's been directly copied from a disk that has some specific codes. Any more thoughts? Thanks.
