I'm considering buying a DVR from Comcast. $.99 TV shows rentals aren't cutting it yet with the exclusion of so many networks, though I'll look back into them when every major network as well as HBO and Showtime are on-board to offer episodes the night they air. Is there a decent possibility that I can connect a DVR to the Apple TV through their USB ports and play videos on the Apple TV, possibly with an automatic commercial skip hack? That would be a really great jailbreak hack, but is this something people are typically interested in?
