I'm using CVS from yesterday morning. When run with no arguments it says
it's 2.1 beta. I can't find any actual download of 2.1 beta, only 2.0,
which doesn't work at all (it prints "Error: Pulse coding not allowed in
short blocks" a few dozen times and doesn't do anything.

I could be that my CVS checkout is broken. I had to fix a couple minor
build errors to even make it compile.

Or, perhaps we're not even looking at the same file.

$ md5sum chroniclesofnarnia-pre_h1080p.mov stream.dump

The usage information says "Down matrix 5.1 to 2 channels", so maybe my
file actually has only 6 channels.
