Do you think it would make sense (if not already done) to have the patch 
switch modes (to 1080i) based on the channel / recording? I tried the 
1080i mode lastnight and although it looks good, the video is not as 
clear as before because of the extra video scaling it has to do. I run 
at 888x540 and it looks really good. I think we would want to switch to 
1080i only on channels or recordings that are from an HDTV source, or 
maybe DVD's.
