transcode has tcprobe, which tries to get information about audio and
video from a media source. He also indicated that he might use
mencoder, which implies that he might have mplayer as well. Running
mplayer in a console with the -v flag set gives you a ton of information
about what's playing.

I really appreciate all of the responses so far. The one command that I
have found that gives me most of what I need is:
mencoder -msglevel all=6 myfile.avi -o /dev/null
It errors out but before it does it drops a lot of information about the
file.
I will try tcprobe when I get home. I don't have any of the problem
avi's here at work.
