Direct TV gets info on viewers through those same phone lines. They can tell what channel you are watching...when we have had trouble and have talked to customer service, they say things like "you're on channel 360 now, right>"
So, I always switch channels or turn the TV off when I am aggravated. Muting won't send the message I want them to get.
Thanks for explaining that. We have cable but my husband is considering satellite and if we go with that, I'll have to remember. Because there are certain shows I just can't give my "vote" of approval for.
