Yes, it works fine. I just encoded the ogg file myself with oggenc
specifically for the purpose of putting it in an avi file.

This only happens once it's been put in the avi file with -oac copy...

One strange thing I noticed is that mencoder is doing the audio copy
with the CBR audio code instead of the VBR code; however, forcing it
to use the VBR copy makes no difference.

I'm using mplayer CVS from last night and the latest vorbis libs.

Should I upload the files to mphq? I tried again with some different
files and got exactly the same results, so I doubt they'd really be
useful. It should be easy to reproduce this problem with any ogg file
and movie file.
