Just got my Tivo and am noticing ads everywhere. For example, when I pause a show, I get an ad with a gold star or something. What's the deal? I paid > $100 for my unit, and $20/month for service. When I called Tivo, they said they were ad supported. How can that be? If they want to show ads, then they should lower the subscription cost or do away with it entirely. Any way I get unsubscribe from these ads?
