Rich,
This may be more than you want to bite off, I'm not sure what the
budget or importance but this is how the pro's usually do it: audio
repeaters...

I'm not sure if BBI still makes the system Bernie uses:

Throw some powered loudspeakers on the outputs, and a little
programming you have a yourself a synchronized, repeatable audio show.

Of course if you still want to use the DVD player idea, I think that
is valid too.  I have been using a consumer grade Panasonic universal
DVD player with discreet 5.1 outputs to play back DVD-A (for audio)
surround recordings that I encoded in Discwelder.  Discwelder Steel
allows you to output 6 channels of 24/48 audio on a DVD, uncompressed.
 The Panasonic deck cost me about $100. (three years ago)  Problem is
that it outputs on RCA connectors.  Lucky for me, my powered monitors
have RCA and XLR inputs on them.  Powered monitors, I remember
thinking that Audix had good powered monitors for the price, it'll
save you on the amp and decoder issues. (Audix PH series)

Good luck,
