It is worth a shot, not sure about how DirectTV will read your inactive receiver though.
You might just have to stick with recording 2 shows and watching the 3rd on hulu.com or whatever website the network uses to put up their free episodes. (hulu.com has all NBC and FOX shows from all their networks)
I currently have directtv and a receiver that records 2 shows at once but with the fall shows coming up, I need to record several of the new shows at once. I also have an antenna for local channels attached to the TV. I have a directtv receiver I am no longer using that I could move to this TV. Can I use the old receiver I have just for the local channels off my antenna
