True. Although i try to get both video and audio bitrates down as low
as possible so as to keep filesizes down (usually for sharing files,
archiving i go for high bitrates).

I don't have any Windows machines here, so have been unable to test it
myself, but i have produced short experimental clips which i've asked
some Windows users on my news server to test.
Encoded using libavcodec some people have had problems viewing them
unless they have either DivX5 or ffDshow
(http://sourceforge.net/projects/ffdshow) installed. Once those are
installed all clips have played back fine, no matter what settings i
have used for audio or video.

96kbps should be suitable for action films, but you will most likely
notice problems with things like explosions.
In most of my encoded files that i share i usually use a 56kbps - 64kbps
MP3, which works fine, but most of my files do not contain complicated
Personally i can't wait until Mencoder supports Ogg Vorbis for audio.
Compiled Vorbis from CVS a couple of days ago and the improvements over
RC3 are amazing. A q0 file (nominal bitrate of 64kbps) now sounds as
good as a 128kbps MP3.
