[mythtv-users] Playing h.264/acc with a Stereo only TV?

[Matt Goebel]

One of my TV's is a couple year old Samsung DLP.  It can't handle 5.1 
audio on the HDMI port (no sound at all) so I'm using stereo.  I have 
another LCD that can, so I have 5.1 setup there.  This hasn't been a 
problem until I attempted to play an H.264/ACC encoded video... messed 
up audio on the stereo only TV, LCD TV is fine.  Analog outputs have the 
same problem.  Is there some way in Myth (or at the OS level) to tell it 
to down convert the the audio to stereo without having to transcode?
