I need to cramp about 3.5 hours of video onto a dvd5, so the max video bit
rate I can use is around 3Mbps.

I tried tmpgenc and main concept, both produced acceptable result but when
there is fast motion, I see blocks.
Strangely, if I encode at 6Mbps, I still see blocks with tmpgenc but
main-concept is smooth.

Both are run using 2 pass vbr at highest quality. I thought the idea of
2-pass vbr is to distribute bandwidth where needed. That means tmpgenc
should allocate some bandwidth away from the non-action portion to the
action portion, which means I should see blocks everywhere, not just where
there is fast motion, right?

If I use main-concept to encode the video at 6Mbps, then output the dvd to a
folder and then run DVDShrink on the folder, would the result look better
than if I encode everything at 3Mbps?
