With regards to a Tivo/cable card - is the cable card linked to a billing account, an IP address, or both? For example, my provider is Cox, as is my neighbors. Could I take my TiVo over to his place for a few days and watch and record as long as his cable is up and running? I wanted to give them a decent demo, and figured the best way was just leave a unit with them for a few days so they could play with it. I’ve rebooted my router lots of times and forced new IP addresses, so I assume the cable card just needs a cable company account to be linked to. But, if they didn’t subscribe to certain paks or premium channels like HBO, does the cable company have to enable access to those channels at their address somehow? In the old days, they’d stick physical filters outside your house to kill/enable channels. Now?
