I think you're referring to the vertical jitter, which is kind of due to 
the OSD going over top of a frame which moves up and down by one field 
ever frame and is then interpolated out - the only way round this I've 
found is to make the "detail" in OSD quite a bit larger than one field. 
I have my fonts and other such things on the "bulkiest" settings I can 
and no longer notice these artifacts personally. I guess for this not to 
happen things like the OSD would have to be overlaid after the 
deinterlacing process - I thought this might be the case with XvMC where 
the card plays some part in the decoding, but it made no difference.
