Oh yeah, one more thing :) I thought I read that some or all of the  
unichrome chips had a limitation on video out where they could not  
output 1280x720 (720p) video or above. Obviously this is a problem if  
you're trying to hook your unichrome based board to a HDTV that wants  
to accept either 720p or 1080i input sources.

I went looking for where I might have read this can couldn't find it.  
Take this with a grain of salt and consider it something to follow up  
on before purchasing a unichrome based board for use with HDTV displays.
