I currently have a series 2 Tivo unit (9410) that has been working perfectly for many years. I received an email offer for an upgrade that includes my keeping my current service plan. I consider this a decent offer since I am paying a yearly amount of $129. Since I only have analog cable, it looks like the only Premier unit I can use would be the Premier 500GB 2 tuner. Trying to compare the specs the best I can, it looks like my present unit has a 40 hour capacity. The Premier 500GB unit says it has a 75 hour HD capacity. Well I don't have HD, so I am wondering how much analog capacity the Premier unit would have. Other than a larger capacity, I like the idea of having a disk usage meter - something that I would really like. Other than the capacity and the disk meter, is there any other compelling reason that I should think of upgrading? The upgraded unit would cost $99 right now with keeping my current service.
