Comment (by oli.henning@…):

 You are righht, the PMT changes at TS-packet number 1644468 (when start
 counting with 1).

 I truncate the original MPEGTS-file to 1644467 packets ({{{dd
 if=original.mpg of=2109_20130701213000.mpg bs=188 count=1644467}}}). The
 resulting file is 309'159'796 bytes long. Then mythtranscode has no
 problem: it identifies all of the 3 audiochannels and the transcoding-
 result also has all channels

 But if i take just __one more TS-packet__ (this will be the packet "PMT
 Version 13" with the changed audio-channel-config, see previous comment),
 then mythtranscode fails as explained (MP2 identified as MP3, all audio-
 streams get lost, and so on...)

 You should be able to reproduce it with the given example-file in my
 Dropbox.
 And i think this is a "hot scent".
