The similar thing happened to me with gxine on Ubuntu 8.04.1 using "intel" video driver in my xorg.conf, but xvattr reports attributes which seem to be normal.
The problem might be not with XV_* or not only with them. While MPlayer plays anything just fine (except of crashing with sig11 from time to time), first run of gxine distorts colors up to the end of X session (no actual reboot is required, only X session end).
