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.
