Ah. So you're commenting on the quality of the desktop. What you're 
seeing is probably as good as it gets. Computer desktops weren't meant 
to be shown on interlaced displays. Myth should look fine though, 
because in contrast, it *is* designed to be run on an interlaced 
display. If I drop to the desktop and try to do a whole lot of work (on 
my Myth box hooked to a 27" analog set), my head starts to hurt, 
because is constantly jittering up and down. TV looks great though. In 
contrast, I have zero problems working on my Myth box hooked to my 
HDTV, which uses a progressive-scan signal.
