Need some insight

[fernalfer123]

I have the Yamaha RX-V1700. I have it hooked to my TV via Digital Optical Cable. I have my receiver set to straight. So a Dolby Digital signal is coming thru while watching HDTV with antenna. FOX that is. Why is it that when the actual program comes on it sounds a lot quieter and when it is commercial time my speakers explode with power and the 5.1 surround really kicks in.

It sounds good like that until the damn program we are watching comes on.

Why is that and is there something i'm not setting right?

The commercials usually aren't in DD but the real problem is that commercials are recorded at a much higher level than the normal program to get your attention (although for most of us it has the opposite effect and turns us off).

The movie has a much lower average level so there is a large dynamic range between the dialog and the explosions.
