Advertisements I have a series 3 Tivo and just received a notice from Cablevision stating "Please be advised that some high definition channels will soon require a digital cable box. As an Optimum customer with a CableCARD, you will need to connect to an HD digital cable box to continue watching...." and they list about 15 channels. I called Cablevision and "soon" is May 1st 2008. Tivo support has told me that even if I connect an external HD cable box to the Tivo, the picture will be standard definition and of course you lose the Tivo automatic recording functionality. Unless I'm missing something, it appears that Cablevision is making it impossible or very difficult for Tivo users to receive those 15 channels. It also seems that Cablevision is attempting to compel Tivo subscribers back to their vanilla DVRs. Anybody have any thoughts, suggestions or workarounds? Thanks in advance.
