Your point about the TV doing the deinterlacing is definitely worth
investigating. However, I have heard this can be quite difficult to
configure correctly. My guess is that someone will get the itch in the next
couple years with the growth of tiny frontends with Intel graphics.

I know I may be oversimplifying this, but I will ask it anyway. Has Intel
already added all of these video enhancements to the linux driver, but
MythtTV needs to add the appropriate API calls at the appropriate times to
utilize the new stuff? I am not saying this is trivial. I am just looking
to understand the current state of things.
