I wasn't necessarily assuming you'd use it on a day to day basis -
just trying to find out what does work for you as a starting point.

It's worth pointing out that it probably doesn't matter whether you're
display using 480 or 720p/1080i. With the former the tv does the
scaling, with the latter your video drivers/card do it. In fact, if
your tv isn't 720p/1080i native resolution it will do additional
scaling anyway (but probably OT).

The GUI does look much better in 720p though!

Can you post some using 1080i, no deinterlacing and openglvsync and
720p, bobdeint and openglvsync.
