5.1 channel through analog?  I must really be out of it.  When I think
of analog I think of 'stereo' (i.e. red/white RCA jacks).  Assuming I'm
thinking of the right thing I wasn't even aware that you could do
anything other than 2 channel audio with them.  I've simply been using
the coax/optical pass-thru for so long I never even thought twice about

So would this would be similar to the PCM output options seen on a lot
of DVD players?
