Kerneldeint has already been integrated with Myth.  This is one of the 
better deinterlacers around - better than the built in one for example.  
Read up on the "filter manager" for how to enable it.

There are also already hooks to do a lot of clever filtering in Myth, 
for example I would be interested in a higher quality resizing 
algorithm.  This would significantly boost sharpness, and most of the 
hooks have already been added to do even this

If you want to do non-interlaced playback though then you are going to 
have to dig a little.  There is some support added recently for the via 
decoder, but I think nvidia lacks interlaced output modes on most of 
it's drivers...
