Overlay bug: XviD and jumping dots

[-Yabba-]

Hello all ... I have a similar problem with Xvid, my graphics card ( ATI all-in Wonder 128 ) won't display overlay in YV12. It only shows green lines. Xvid movies always default ( for me at least ) to YV12 and I can't find a way to make them use YUY2. Overlay Mode 2 makes BSPlayer crash, and finally disabling overlay makes the movie watchable, but really bad ... it looks pixelated. Besides, WMP 8 shows the movie perfectly ... but I can't have subtitles and anyway I prefer BSPlayer and not Windows-crappy-Media-Player.

Am I doing anything wrong with BSPlayer ? Or maybe I'll have to wait for new build to force it to use YUY2 ?

BTW, I tried some different Xvid implementations, and also FFDSHOW, with same behaviour. FFDSHOW also uses YV12, even in Divx content ... when Divx codec used YUY2 normally.

Thank on advance for your help ...
