I guess you're probably still a young fellow

None (at present).

It is very possible! The 'hi-res' matrix does not roll of higher coefficients
for inter-coded frames at all. As such it only sane if you have LOTS of
bits. If you have less bits a matrix that trades

So how usable is 2-pass encoding with 1.9.0-rc?
Hi Andrei,

Not at all useable - there's still some bits not yet programmed. The -A 0
stuff is all there and up and running already.

That's excellent. Currently I set the max bitrate to

Current cvs compiled fine this weekend on a SuSE 10.2 system so it
is puzzling why the problem:

CVS compiles fine on 7.10 if I use the same -lX11 patch.
