I have a series 3 and recently bought a Sony HX850 46 inch LED tv. I'm wondering whether a new Tivo is in order for a couple of reasons. First, the Netflix service through the Series 3 is quite bad. I did a comparison of Netflix on the new TV (it's an option) and the quality is much, much better. Second, the new TV does 1080p, and I see that the Series 3 supports only 1080i. Would the new Tivo result in a better picture over the Series 3 with my television? Are there other reasons to upgrade the Tivo other than the ones I've noted? Thanks.
