Error on enabling ffdshow Decoder for Xvid,Divx !

[wesmosis]

i don't kow why I'm having an error when ever I enable the ffdshow for avi files, and playing them in BSplayer :

Code:

Warning
Unknown File Format (YV12)


and other times this message (this when I put XVID as Decoder)
Code:

Warning
Unknown File Format (XVID)


also when I change the Decoder in ffdsho to Xvid, the same warning appears

while if I DISABLE the ffdshow they works perfectly
but I need the ffdshow for many
by the way, ffdshow works perfectly with any other players like MPC


btw I'm using always the latest ffshow versions
and BSplyaer Version 1.36.825
