I have actually been contemplating doing this for some time now. I have 
just been living with it. I used to disable deinterlacing when watching 
HD content and re-enable it when watching standard recordings, but now I 
just leave everything deinterlaced and live with it. HD looks best when 
it is not deinterlaced because I am using a hd interlaced mode on the tv 
for that content, but standard def shows show slight tearing if 
deinterlacing is turned off.
