First off, please CC me in any replies. I recieve the daily-digest, so
it will take longer for me to see the message, and be a little more
difficult to reply, otherwise. (more below)

It's obvious that it isn't as good as the source. It's a very rough
picture, and it get's VERY blocky when there is a lot of movement. This
is from a source that wasn't all that clean to begin with, so it's a
major step-down in quality.
In addition, I have successfully encoded it with vbitrate=1200, and the
resulting file is 1.1G. Unfortunately, I didn't log that pass, or I
would provide you with the output. I can encode something else (and log
the output) with any parameters you please, if that would be of any help.

If someone would like to provide a set of patches to allow MPlayer to
compile on OpenBSD 3.2-stable (a port/package would be even better) I'd
be happy to upgrade. Otherwise, I plan to wait until there is a
non-fractional release available, before I do some work on porting a
newer version of MPlayer.
