I've been outputting nothing but a 1080p signal to my TV for the past  
4+ years or so, without using a deinterlacer. MythTV handles the  
scaling of everything that needs it just fine, the TV handles the  
deinterlacing, and everything looks quite good. (And the bulk of my  
content is 1080i mpeg2.)
