When I burn it works fine and the burnt DVD will play fine on PC. It's my DVD player attached to my TV that is the issue. When I place the DVD in the player attached to the tv, I get 'Disk Error' from the player!.
We don't often get problems with playing a burnt DVD.
Not sure is the short answer if it plays on PC ok? have you tried it on other normal dvd players etc?
Only thing i can think of is perhaps the physical blank disks themselves are not compatible with the player. Also make sure you are setting the pal/ntsc setting correct in the burn wizard, but can't imagine this would cause a 'disk error ' in the player as such.
