Which settings are those? chromakey or ia44 OSD? Which deinterlacer?
What XvMC hardware are you using? VIA, nVidia, other?

If you use the OpenGL OSD with XvMC then you will of course have
much worse performance, but you would know if you were using this
OSD renderer because the OSD would look much better.

I would need to see the logs. Bob deint will only work if the refresh
rate is high enough, and the 'none' deinterlacer will never load. I'll
make sure we don't print anything confusing to the log in this case.
