I have a very simple setup, Motorola HD DVR connected to Onkyo 607 via HDMI. I ran the Audessy Setup sucessfully.
Most channels sound great. However, certain programs, on certain channels, have very low "dialogue" type volume. Even if I increase the overall volume, it sounds terrible/distorted.
When the cable channel guide on the TV says "5.1" the sound always sounds great. When its missing, thats when the problem can occur (not always, and agian, one program on CBS HD might sound fine, and then when a new show starts, it can sound afwul).
