I have two series one tivo units work great, expect now Cablevision is going completely digital. So the unit will not work as of aug 23, 2011. So I called Tivo and told them I am interested in upgrading unit & I have an existing Lifetime on the boxes. Tivo $399 to upgrade to a livetime on digital box and about guessing $200 for a premier box. So I told Tivo I can rent from Cablevison their DVR box for $10.... that is 120/yr. So it would take me 5-6 years to BREAK EVEN. and by then technology may have changed again. Tivo wants to keep customers I do not think so..... not at $600-700 to do an upgrade.....shame on Tivo Curious, what is the response from other on these situations?
