	I always use latest svn. In this case I tested with 29418 svn

	Notice that MPlayer chooses AUDIO PID 4355 (wrong language).

	Here is the relevant output with -v option showing how many AUDIO PIDs MPlayer can detect:

==> Found audio stream: 0

ADDED AUDIO PID 4355, type: 2000 stream n. 0

==> Found audio stream: 1

ADDED AUDIO PID 4353, type: 2000 stream n. 1

==> Found audio stream: 2

ADDED AUDIO PID 4356, type: 2000 stream n. 2
	
	That's all MPlayer can detect. Just the plain AC3 audio tracks.


	If you want all the -v output I can send, but it's huge, so I'm afraid there's an 
attachment size limit here, even if I compress it.

	The correct AUDIO PID would be 4352 which MPlayer doesn't even detect. The proof is given 
by tsmuxer output (which detects correctly all audio PIDs:

	***

	So, as you can see, MPlayer has a problem detecting only the "TRUE-HD" stream types. If I convert AUDIO 
track 4352 to AC3, MPlayer will detect and play it fine.

	The correct behaviour would be to use audio track 4352 (English) by default and not 4355 (Thai). The others 
are: 4353 (Spanish) and 4356 (Director's comment). And there is another TRUE-HD track (4354) which is Portuguese.

	So, to sum up, there are 5 audio tracks, but MPlayer can detect only 3, which are the AC3 ones, ignoring
the remaining two TRUE-HD tracks:

4352: TRUE-HD (English) 
4353: AC3     (Spanish)
4354: TRUE-HD (Portuguese)
4355: AC3     (Thai)
4356: AC3     (English, Director's comment)

	MPlayer only "sees" 3: 4353, 4355 and 4356. I know it because, besides the output, I can cycle through 
the available audio tracks and it give me only those three ones.

	Thank you. If you need more information or some test, just ask.
