Hi magre,

Make sure that your DVD player is connected with an optical or coaxial digital cable to your 2500, and that you have the correct digital input selected. Your 2500 should automatically switch to Dolby Digital 5.1 and indicate that.

I'd suggest you try a manual setup of your system as well, using a Radio Shack SPL meter and a setup DVD like the Avia disc or the Sound&Vision Home Theater Tune-Up.

The auto-setups on these new receivers are prone to errors.
