Most of the channels are in 1080i I believe. One thing to keep in mind
is that if the the original signal is 1080i then it has to get
deinterlaced somewhere. If you set your STB to 720p then it is doing
the deinterlacing. If you keep it at 1080i then the you can let
mythtv/GPU do it, or you can even do some work to get it all the way
to your TV and let it do it. My point is that setting your STB doesn't
get rid of the the deinterlacing issue it just moves around where it
gets done. I would bet that VDPAU does a better job than most cheap
STB would do.
