the way i understood it was that Apple's osx dvd player is software baised... which leads me to believe that the graphics card is irrelivent.
my question is then what do you need to play a dvd on a mac? i seem to remember the there were g3 400mhz that worked, but i am not sure. if that is the case, is it possible just to add a dvd rom drive to my imac (revb) now that i have a 400 mhz upgrade in it. obviously it would have to be a laptop drive, but i would be interested in trying.
