If you want to place bets on "Idol" in Vegas, we think we found a way you could score millions of bucks. TiVo may have cracked the mystery of who gets kicked off and who doesn't. Company insiders say they can predict who's not connecting by TiVo usage.Here's the deal. In a sample of 20,000 users, TiVo monitors traffic -- which contestants get replayed (a sign of popularity) and which one's get fast-forwarded. You think it's bogus? Well, the TiVo system has nailed who got booted four weeks in a row. And who does TiVo say is getting the ax tonight? Poor Syesha. Take it to the bank, people.
