Gonk's post noted.
The site to which I referred has many good dts discs. This is great multi-channel material...many of which were recorded as such.

Additionally, DVD players will decode the discs, though there are outboard dts decoders for those who wish to play their dts discs thru regular CD players (must have digital out for this of course).

And as I write this I'm listening to a dts disc thru a Sony 455 changer, decoded by a Millenium dts decoder into 990. Yes it displays the fact that it's got a dts signal.

So guys enjoy multi. DTS really has great separation. When a DVD has both dts and DD I choose dts.
