Also, when I set "Max audio channels" to "Stereo" - the frontend messages
show that the 5.1 recordings are only seen as having 2 channels.

I'm wondering if maybe there's an issue with setting my receiver's mode
from within Myth - the problem I originally posted on was playing a 2.0
source AFTER playing a 5.1 recording *using the Myth internal player*. 
This doesn't happen when using mplayer - I can go back and forth without
any problem.   The receiver is an older Kenwood 5.1 unit (VR-407).
