I see try to see a divx ripped at 640x357 on my Zaurus C3100 running Cako 1.23 and mplayer with bvdd... all works very well but the video seems not at 357 because there are 2 black bars very heigh....
The same video on an Dell axim x50v played with TCMP is more bigger : the video's height is more correct then the same video on Zaurus....
