don't know why it says it twice, don't know why its not initialized there with the other things

hmm, can't see anythign off really. does x11 output work? mplayer file.avi -vo x11. i'd guess it's a problem with file itself, as mplayer does say somethign along those lines.

yea it plays with X11 in mplayer or xshm in xine
