[MPlayer-dev-eng] bug on mpeg-ts demuxer... or something like this

[Alejandro Vargas]

It is not a real bug but a problem. Mplaer now plays correctly mpeg-ts
files, and reports correctly all video and audio streams, but seems to
be selecting the LAST audio stream instead of the first one if no one
is explicity selected via -aid <audio_pid>.

The problem is not big but I think it would be more consistent to use
the first audio pid instead of the last one.
