If I'm watching a game in hi def it's on the big screen, as a result I've got it on the stereo as well for the dolby. Then I just turn down the volume on the front and center channels, turn up the volume on the surround speakers, and I hear the crowd and the stadium announcer instead of the tv guys. It's a much better way to watch the games IMO. Unfortunately I can't turn the front and center speakers down completely on my stereo, I'd have to unplug them, but the tv announcers are reduced to a distant murmor that's covered by the crowd noise and stadium sounds about 90% of the time.
