ok i bought a mac mini for the sole purpose of using it as a media center. previously i used an old power book g3 to stream itunes music to my stereo in the living room. my wife uses her pc to record tv shows (tivo like). my main computer, a dual 1.25 g4 in the game room has no problem logging onto her computer and playing the media files. on the mac mini, i cannot get it to play the mpeg videos, computer says "QuickTime cannot open the file: "0037.MPG"it is not a file that QuickTime understands (-2048)." i have even tried using microsoft media player for osx. it does not play says unsupported format. this does not make sense to me because on my wifes computer when she opens the same file it opens in windows media player. does anyone know what to do. please help
