Hallo Richard,

Thanks for the help.

Yes, it seems that width and height are wrong. What I don't understand 
is way could I play the file correctly with some previous version of 
mplayer. Currently I can also play the file correctly with mediaplayer 
in windows and the 3ivx codec. And even quicktime can play the file. So, 
how do they do it? They just "guess" the right size?
