The multiple audio stuff is only partially implemented anyway. No one 
has shown much interest in it. If you have some code for me to take a 
look at I could probably rework it to work with the multiple audio 
channels.

I seem to remember that the old mythburn scripts had to use the log file 
produced by projectX to find the correct audio stream to use. How are 
you doing this, is it done in python or are you calling external bash 
scripts?

Thats no problem. I've been taking a break from working on Myth for the 
last 3/4 weeks anyway.

Jeff Hausheer is the main developer of the lossless transcode part of 
mythtranscode.  I think he must be very busy, I never got a reply when  
I tried to contact him about the problem with audio sync after cut 
points problem.

I don't think it would hurt to add support for projectX so long as it is 
optional. It does mean having to support two lots of code that do the 
same thing but there are just too many people having problems with 
mythtranscode so I think its worth the effort.

Mythtrancode removes all streams that aren't either video or audio. 
Fixing that would require TS -> TS  rather than the TS -> PS that 
mythtranscode does now. I don't think that will happen any time soon. 
projextX can extract the other streams when it does the de-mux.
