well, using the settings at the bottom of that page for "Very High
Quality" I'll say, the space saving are incredible, roughly 1/5 the
filesize of the mpeg2 encode, the problem is, still not as sharp.
Playback on a 50"+ screen will show noticeable difference between the
two.

I'll have to go through the information on that page to try and find
suitable settings for doing a true very high quality encode. Slightly
higher bitrate should do the trick I think, so its just a matter of
playing around with the settings.
