The installer that came out to install my cablecards did not seem to really know "how" to do it properly, and with no surprise, a few things are not working properly. This is on a Tivo HD with Cablevision service. I got 2 cablecards and was trying to figure out what was setup incorrectly. I am able to receive all channels that I pay for on the first tuner, but when I switch to the second - it seems to work for most stations but the premium (e.g. HBO) end up sending me to a screen for my CableCard 2 to have it activated. Now, I know that this was activated but before I contact cablevision and do more trial and error, I wanted to make sure that something else isn't to blame. Currently only the digital coax cable is connected as the cable guy said that you do not need to hookup a splitter and connect it to the analog connector. Is this correct? Any advice on what I should look at next is GREATLY appreciated!
