[khayos]

The following was all completed with a fresh rebuild (including 'make
distclean') of MPlayer-1.0rc1.  There are a lot of long pastes in this
e-mail, as requested, but please make sure to read the very end for
the victory tale.

NOW, here's the interesting thing.  It may be the clean build, it may
be the latest version of mplayer, but this time around when I tried
"-ac ffdts"... it worked!  I have sound!  So I'm not sure why ac3
didn't work, but the question now is academic.  I can go watch my
movie!

Thank you all for your help, it's greatly appreciated.
