Sorry, I only read the first half of your post. recordmydesktop will
only output ogg theora files AFAIK.  xvidcap OTOH can output in a
variety of formats and also write to a unix pipe, so theoretically you
could do:

mkfifo your_pipe
xvidcap -your_flags --file - > your_pipe

Then open the named pipe in your video player of choice. I've found
xvidcap to be pretty flaky and tricky to figure out though.
