There used to be a time when you could get 1 or more premium channels added, but not any more. You have to get the whole package, or you get nothing. And besides, I've had plenty of instances over the years where the one DVR I've got either hasn't recorded the program I'd set it for (says channel not available), the program I recorded is all pixelated, and can't be viewed, or their system freezes while I'm recording, and I have to reboot the box, and lose the full recording. So why would I want to double my displeasure and have whole house DVR, and pay more for it.
I don't watch any live TV. Everything I view is recorded so I can fast-forward through the commercials.
That is why I don’t have a DVR anymore. I just built a computer that has multiple 2TB hrs and I bAck up everything via a handy little program a friend wrote for me. The program also has a streaming record mode like DVR. There are freebie programs that do the same.
