unfortunately aid 0 is not the only track present:

0000b822: picture hdr, frametype=0, temporal=0
0000b83e: pes audio 2; length=184; hdr=2; pts 64299.554 sec; 
pstd=830464 (scale=1024)
0000c122: picture hdr, frametype=0, temporal=0


the first track is aid 2, that vanishes soon thereafter.
It's not the first time that I see a mess like that, but
adding some more detection magic (like removing too short
audio tracks) would result in more arbitrary code in an already messy
demuxer.
For your convenience pressing # will change audio track on the fly
