No, that won't help.  If the source material is 1080i then the incoming 
resolution simply *is* 1920x1080.  Even if you display that 1920x1080 on 
a lower resolution screen (which is what 720p native HDTVs will do), 
then somebody still has to decimate the video down to the target 
resolution.  But you *still* have to decode the mpeg2 stream as 
1920x1080 first and then scale it down.  Thus the mpeg2 decode overhead 
doesn't change and somebody has to spend cycles to scale the video 
(probably / hopefully the GPU).

Ha.  Nice.  Sorry but these days the demands of emacs are trivial 
compared to just about everything else.  Well except maybe vi.
