Dishnetwork inserts their ads at a much higher volume than the networks they carry -it is devasting on HD channels when you have your surround system running. New Year's Eve was the worst and it blew out the center channel of my Harman Kardon AVR system.
While watchning CNN's NYE coverage, in High Def, I had my system fairly loud to enjoy the events. Next thing I know, DishNetwork inserted an ESPN or some kind of sports PPV ad -it was so loud, I don't recall the exact commercial, but it ended up blowing out my center channel. I am so friggin' pissed I can't see straight. I've written them with my complaint -I'll update this when I get a response.
I'm also going to file a complaint with the FCC because a quick internet search reveals that I'm not the only person who has been affected by the volume of their ad inserts.
