Wierd. Any PAL DVD Player is required to support mpeg2 audio and it may
optionally support ac3, but doesn't have to. Givedn this standard, you'd
expect a player to actually play mpega audio without any fiddling
around. But OK, that's what happens when reality meets standards.

So, a better solution would be: 
	1) let users specify their preferred audio format (mp2 or ac3)
and
	2) allow transcoding if the preferred audio format isn't
available in a recording.

That's the first thing I had tried - didn't work. Only difference: the
demuxed audio files are saved as *.mpa by projectx; looks like ffmpeg
doesn't recognice the mp2 audio file with an .mpa extension but works
just fine with the same file renamed to .mp2. Aaaarrrrgggghhh!!!

Thanks very much for the hint.
