I have it working with another un-named vmedia player :) on the same file on the same system. Just can't figure out how to convince mplayer to do the same. Some other posts seem to imply it might be possible, but I have not been able to replicate that result.

OK, your mplayer version isn't the newest, indeed, the code to support
of ac3 output on macosx was commited just after the 1.0rc2 timestamp.
But you can found the usable version of mplayer in the MPlayer OSX
1.0rc2 in the mplayer's download page, it use some later code of
mplayer, and have many very useful improvements.
