Ah, Ok. I see.  Then this will definitely work (provided you machine
can handle simultaneous encoding and playback):

First make two fifo's for piping video around:
$ mkfifo rawvideo
$ mkfifo encodeme

Then use mencoder to grab the video and audio from the devices and
combine it into one stream.
$ mencoder tv:// -oac pcm -ovc copy -o rawvideo &

Pipe the stream through tee(1) to get one for encoding and one for viewing
$ cat rawvideo | tee encodeme | mplayer - &
$ mencoder encodeme [options] -o archive.avi

You might need to add some options when reading from the fifos to get
mplayer (mencoder) to recognize the stream but the concept will
certainly work.
