No, I think that to watch as well as simultaneously record to their DVR unit you only need a single coax cable from your dish.
Well that’s good to hear. the reciver I am thinking about upgrading is in a place where it would be a real pain the butt to try and snake another line into the room through several rebuilds and floors. It would be easier to just route two new lines outside the house, and drill into it. Something that would be a deal breaker for me. I like the idea of the DVR, but I am irked that DirecTV is now charging $6-$7 a month, for what I used to get free with the purchase of my old receiver. ..Sounds a lot like they cut the competition out and had a new way to jack their prices. :-(
