[mythtv] mythtranscode dropping audio?

I noticed this while working with mytharchive and opened trac ticket # 1841
Chris asked for a sample, but I have no easy way of sending my file so I 
dropped it. (my bad)
If you can get a sample, you might want to attach it to that ticket...

In any case,  I dug into the code a little and I found it wasn't reading 
far enough into the stream
to see the audio tracks. The attached patch works around this problem by 
greatly increasing the
"how far should I read to get stream info" parameter.  It's a hack but 
it worked for me. YMMV.
