Hi Folks I checked out the dell xp machine and the G4 with a commercially made dvd here is what happens In the xp machine windows media player opens up In the g4 the movie opens up perfectly on a full screen with the controller The dell running win 98 wont open the film at all! Question why do commercially made dvds work on both mac and pc when a dvd burned on the mac will not open on a win xp that can play commercial dvds?
