Commercial zappers

Yeah I know Tivo lets you do this, but of the products on the market that say that they can zap commercials live, are any of them worth a lick? I’m watching the baseball playoffs and often am blogging on the web about the game while the TV runs in the background, and Lord if I hear John [del]Cougar[/del] Mellencamp’s “Our Country” again, or that fucking Gecko, I swear I’m getting out my shotgun and getting more than little ornery.

Ummm…I don’t see how this can work. If you’re watching something as it’s happening, there’s now way to skip the commercials to get to what hasn’t happened yet…especially with a LIVE baseball game. Have you tried just muting, so at least you don’t have to hear it?
