Yeah, works well, although I found that I was suffering some drop outs,
so I grabbed David Barr's mods that intergrate the ac3dec stuff, and that
seemed to improve things hugely. Still not perfect, but I need to do some
more realtime work on my kernel anyway.

I also suspect that mplayer was creating some issues. Anyone know of
another video player with jack, and framebuffer support ?

Ah ha. Perfect. Thanks.

Ah gotcha. I was getting confused with thinking the bus was doing
surround sound stuff, rather than just applying the panner.

Heh. Oh I pushed jack even further :) Just for kicks, I tried 6 
channel audio fed via jack.udp, using a 802.11g network, out via
ac3jack...Must try it with QoS next time...

Thanks again, for clearing up my confusion
