Carl,

With your patch, the resulting .wav file waveforms look really bad 
(severe phase reversals), so something is not right.

I can't say for certain it is wrong, since I have no way to know what 
the audio is supposed to look/sound like.

I spent a few minutes on http://www.coolstf.com/tsreader/ to see if they 
document their tool's file format, but didn't find anything helpful.

As far as I know, MPEG stream type 0x83 is not unique. Different systems 
use it for different purposes. In some situations, it indicates a 
Meridian Lossless Packing (MLP) audio stream.
