[MPlayer-users] Problems with expand filter and chroma/luma

Hi
I have problems with video files compressed in WMV (Microsoft Windows Media 8).
When i use expand filter, luma is okay (mostly, in expanded area i see scaled and duplicated
image, i think it's luma), but chroma is scaled, moved (each chroma component has different
offset) and generally something is wrong with it.
It happens only with WMV (i have only two files in one WMM version, so i don't know what
about other versions), h.264 and MPEG4 are okay.
Without expand it works perfectly.
