Okay, I've just been asked to produce a live DVD for a comedian. The
venue's apparently in London's West End so they should be more than used
to having people hanging mikes all over the place and having cameras in
there.

Now, although I don't know of any DVDs in this genre that are 5.1, I'm
adamant that this one will be - particularly as the experience the
viewer should have, if done correctly, really will be like being in the
club.

This is where you guys come in - I'm looking at different ways to record
the audio. The actual miking isn't a problem, but I'd like to leave the
venue with five separate audio channels that I can mix later.

The simplest way I could think of to get the job done was to mix the
three front channels live via a desk that then feeds a stereo signal to
the camera, while feeding the two rear tracks to AN Other recording
device which can be synched later, but that doesn't give me any real
control in post.

Of course, I can simply record the whole thing live and mix it in a
rented studio at a later date - but that option may prove too expensive,
plus how can I guarantee synching the audio with the video?

Is there another way?
