Hm, well, right now it's horribly broken, but works with mplayer -vo gl.

Well, for some reason none of the deinterlacers work with OpenGL on my 
system, even though there appears to be much CPU power left.

Just for clarity: I usually use the kernel(2x) deinterlacer with Xv, 
that would be the "software kernel deint" you mentioned, right? It's 
giving me by far the best results (I use a recorded piece from a news 
channel with a text scroll to verify) so I'd need that one to work with 
OpenGL as well.

I'll keep monitoring this. It appears like this whole issue is made much 
more difficult to track due to very different graphics stacks running 
here and there, so I'd very much appreciate if you could keep having an 
eye on the bug report and other people's observations.
