Oh, Barry, say it ain't so! Why did you lose reception whenever the wind blew - was it trees in the way of the antenna, or was the antenna not secure? I used to have some issues with a couple of stations, but I went to two low-profile antennas (
this RCA model) instead of my
Channel Master 8-Bay (not really for the wind, but I think that they helped). Using an amp/preamp for me was essential (I have the
Channel Master 7777).
Anyway...I don't know if Directv has any sort of copy protection on their video outputs or not.
As for getting two different stations from the same box, do you have a dual-tuner Directv receiver? It has to have more than one tuner to be able to watch more than one station (or record something different than what you're watching).
