Advertisements TiVo sent me an offer to upgrade my premier xl4 to a Bolt and they'll transfer my lifetime subscription for $99. I know that's a hell of an offer that they don't make often. A few months ago my xl4 was acting strange and was thinking it was going to fall. But it's been fine lately. So I'm wondering if it's worth the money to upgrade to Bolt or not. I don't need 4k. Have no plans to get a 4k tv. The xl4 is 5 years old. Should I upgrade simply to have the newer device? Should I get the 4 or 6 tuner? TIA!
