Since the disk plays well on the pc, you’ve probably done a good job of decrypting the disk and getting it to the correct size to fit a dvdr.
Some dvd players are just picky about playing burned dvds. First thing to try is slowing down the burn speed. What type of disks are you using, and what speed did you burn on the first attempt?
Use Nero CD/DVD Speed and open the Disk Info tab. Tell us the mid code of the disks. Please also tell us the make and model burner you are using. That should show up at the top of the window for Nero CD/DVD Speed.
If you don’t have Nero CD/DVD Speed it is free to download and use: http://www.cdspeed2000.com/
