I got a tivo for my birthday, and I'm planning on setting it up with the 1 year monthly plan, but I know that for christmas the same person is planning on giving me a prepaid one year for the tivo. When this happens will the new plan replace my old contract, or will I have to finish out the one year monthly before having the one year pre-paid. Or will the prepaid start in december and then in the following december I would revert back to the monthly? Sorry if that's a little confusing. I'm a little confused!!
