We got our first DVD player earlier this year, and have to this point purchased about 35 DVDs. We also regularly rent.
I looked through our collection last night and didn't see one, not one, that was labeled DTS.
Given that my system and setup is a compromise between "best location" vs. life and kids and all that, I don't know that I would be able to discern subtle differences between DTS from DD, but my receiver is new and I have yet to see that "DTS" light go on...
What DTS DVD would you recommend to check this feature out?
