said by LD 50:So, in my case, say I am watching the Pats on a Sunday afternoon, and my wife has a show on the downstairs DirecTiVo she wants to watch upstairs, she cannot use this to watch it upstairs, since sling needs DirecTiVo to switch to that show. (snip)in my case, a networked DirecTiVo that serves up any show to any TV at any time is what is needed.
Since any self respecting football fan with DirecTV has Sunday Ticket, you'll be using both input lines and your wife will be out of luck regardless. I make my wife leave the house on Sundays....
