Thanks for your answer.. Is there any channel changing speed losses on 
xine-plugin.  How about stability and long time use?? It is important.. 
How about tv-out with graphic card? I see ghosting eliminated with tv a 
little bit.. Is there any way to improve it with tv-out??
Last question I cannot work X with resolution 720x576? Can you write 
your timings here??

Maybe some good deinterlace algorithms can be port to libpp ..
