Roger,

to answer some of the questions, that Larry didn't touch:

- DTS is not available on all discs (yet) becasue it takes up far more space on the disc than DD. I have heard that in US, DTS is some kind of Quality Stamp which generates sales of DVDs, but apparently this phenomenon has not yet reached Europe (where I am), as only very few Region 2 discs have DTS soundtrack. There might also be a commercial issue in including DTS (licensing, royalties or whatever), but I'm not sure

- It could also be that your level differences are caused by the speaker setup. In the extreme there could be 20dB difference between the speaker level in DD and DTS just because of the settings (20dB is a lot!). Try to find the manual and see how you can check/adjust the level (and timing) of the individual spoeakers.

And then finally: Welcome in the DVD-world...
