Thanks to all for the replies. I shall definitely check out some of those titles! Not having heard DTS yet, I must say . . . if it beats Dolby Digital, hen DTS must REALLY ROCK!
I have a new Onkyo 595 receiver and the DD sound is fantastic, and the PL2 sounds good, too, for the appropriate sources, but I haven't listened to DTS yet. Any suggestions for a few good DVDs with impressive DTS sound?
