I just backed up Saw a week or so ago, and it works perfectly fine in my dvd player, but when I take it to friends houses, it doesn't seem to want to play right. It plays, but about 3/4 of the way through, it starts skipping around really bad, and it just doesn't seem to want to work right. I used the same disks as before, and other movies worked fine in them. I've tried to make another copy off the original disk, and i've also tried making a copy off the file that was left on my computer. If anyone else has had issues like this please help me out. I have a Lite-on SOHW-1213s using DVD Shrink to burn with.
