hehe, Well I have win2k FINAL and I must say thet Matrox (cinemaster) dvd player from Matrox's instalation CD in working fine, it is about 80% stable but if I use dualhead-dvd max, the picture on monitor is fine, but one on TV is heavely fuc-ked up.
So I'm using win2k for everything.
For DVD I'm still using win98.
And if you can get anywhere WinDVD 2000 it is working fine with no glitches on win2k.
but as you said, for matrox hardware (g400) the best player is the official Matrox player(cinemaster software).
bye
