Ok, it sounds like this feature is in use. I would have like AC3 testing
too as this changes some of the AC3 code as well (there is a lot of
commonality with DTS encoding).

I thought maybe everyone had given up on it because it doesn't work with
time-stretch. I never watch anything below 1.15 these days, and things
like ST:TNG, SG:SG-1 get the 1.5 treatment. I'm a little unhappy with
the non-working multi-channel audio support in MythTV. I might fix that
in 0.20 if no one beats me to it (w/audio time-stretch of course).

Anyway, it looks like Martin is looking at this. Martin, send me a quick
e-mail when you've merged the changes and I'll have a look at it again.
