I suspect that the problem is that the 'strean type' in the output 
Transport Stream is not properly being set for AC-3 audio.  Note the 
code at lines 109-116 of 
"liveMedia/MPEG2TransportStreamMultiplexor.cpp".  The last branch of 
this "if" statement is supposed to set the 'stream type' for 
non-MPEG-audio to 0x81, but I don't know for sure if this is correct 
(because I've never actually dealt with MPEG Transport Streams that 
contain AC-3 (rather than MPEG) audio).

Unfortunately, I don't know what the 'stream type' for AC-3 audio is 
supposed to be, but if you know, this is probably the place in the 
code where you should change it.
