Thanks Paul, I'm not the only one then. I have checked with the vendor re trying another video card, and was informed, to my disgust, that I have a "domestic consumer" machine that was never intended to do the kind of things that I want to do with it. The video card is an integral part of the motherboard, and cannot be replaced with another, nor can it be disabled to allow a plug-in card to do it's job. I can see the good people at MTU nodding their collective heads about now and saying "We told you so, you should have bought a proven work-station from us!" to which my answer is, if I lived on your side of the world, I would probably have done so. Since I'm not, the only thing I can do is to hope they can come up with a solution. I might add that Video CD, and DVD run on this computer perfectly and cheap and simple Sega Saturn game players will play the discs I burn, and show the graphics. Could the problem really be a glitch in your codecs, MTU?
