Here's a strange one:
Every time I burn a DVD using my wife's computer, the DVD is readable only on her computer. I have tried this with both data dvds and dvd-video. I am burning from files on disk, not from an ISO. These are burned using Nero 6.0.0, Pioneer DVR-109, Windows 2000 server, Fujifilm DVD+R media (Ritek R03).
I don't think it is defective media because I have used numerous discs from the same batch on my system without any problem. The discs are rejected by all DVD players and all other computers, but the data discs read fine on her system, and the dvd-video discs play pefectly using VLC (again on her system only).
If I use cd-dvd speed on another computer, it recognizes the presence of the disc and shows disc info, and shows an ISO 9660 track on the disc, but all of the speed and disc quality tests are greyed out. But windows refuses to mount the filesystem on the disc. Also, the disc status is open, which it clearly should not be in the case of a DVD-video disc.
Anyone have an idea what's going on here? Any help is much appreciated!
