I've burned 5 dvd's and can only play 1 on my dvd player. These were all AVI files that I used WinAvi to convert to VOB files. I then used Nero to burn them to DVD+R Media. The 4 that don't play give me a "Disc Error" on my player, and it says "Playback may not be available on this disc." Saw 3 is one of the discs that won't play and Windows Media Player gives me the following error message when I try to play it on my comp: "Windows Media Player cannot play this DVD because it is not possible to turn on analog copy protection on the output display. Try installing an updated driver for your video card." Does this sound like it could be the reason for my inability to play this on my DVD player? Am I doing something wrong here? Thanks for any help!
