I've got a Phillips mx980d HTIB which I really enjoy. I looked at a lot of similar packages like the kenwood and after listening to them all choose this. Well my quesdtion is two fold. First when using DD 5.1 Thee reciever reads ac3 3/2.1 is ac3 another way to say DD Dts reads dts 3/2.1
? My other question involves different virtual and surrond modes Surrond modes are hall,surrond, pro logic,dd, dts front 3stereo and stereo. Virtual modes are 3d surrond,multi front,multi rear, and natural surrond. What would be the best settings for movies I'm afraid some of the virtual modes might change how the sound comes out by creating phantom speakers instead of goingf straight to the speakers?? Does this make sense or am I babbling??? gracious

Hi drexel. Yes, AC3 is just another way of saying Dolby Digital (DD). It has something to do with the actual digital storage method used I think.

Also, all the virtual surround modes etc are designed for enhancing stereo signals. If a DVD movie has a 5.1 sound track (DD and/or DTS), then ONLY use DD or DTS on your receiver. If the movie only has 2.0 as a soundtrack option, or you are watching TV or listening to a CD, then play around with some of the other modes. For instance, a live concert CD can sound more real if you select HALL or STADIUM or LIVE (different receivers have different options).

I hope that helps.
