I was given a HD receiver (Panasonic TU-HDS20) and dish by a friend. I am eventually going to swap my dish (2LNB) out and put the HD capable one up. In the meantime, I tried to replace my one receiver with the Panasonic in order to take advantage of the component video outputs (my old receiver only has SVideo). I installed it, pulled the programming card rom my old receiver and put it in the new one but get no signal. Is it because I have not replaced the dish also? I know that to get HD reception I need to contact D* and subscribe but can't I use the new equipment until then? What all is involved in swapping this equipment out?
