How do I record PAID cable tv like a DVR (No DVD or VHS) without a subscription?

Ok here's the deal. I need a device that can record just like a DVR but I don't have to pay a subscription. I don't want a DVD recorder, let alone a VCR. But I want a device that does the same but like a DVR, with no disc or video tapes. I looked and looked and can only find devices that record broadcast (local) channels. I don't want this, I need it to also record PAID cable channels (encrypted), basically I need a device that can record anything you hook up to it like a DVD Recorder or VCR. Also I do NOT have a cable box (so no cable card), just a rf cable that comes from the wall. Is there anything out there I can use? PS: Channel Master and HD Homerun will not do as they only record local channels. Moxi won't do for me either as it requires a cable card.
