Yes, I do mean Satellite input line one. When I was on the phone with the rep from Directv, she had me swap the two cables and verified that input line 1 was not working. But it was with the "new" receiver. I'm wondering if I had tried that with the "old" receiver, if I would have found that my problem was just an imput line 1 problem, and not a receiver problem. When I first had a problem with the receiver, it was a frozen or paused image on screen. I shut the whole thing down and restarted it to get the message "just a few more minutes..." for 6 hours. That's when I called Directv. At that time, they said it was hard drive failure and the satellite input lines weren't even tested or switched to see if it was an imput line problem. What do you think? Could it have been? I'm not kidding when I say I was on the phone with them for over 3 hours yesterday so I hesitate to call them and get the card activated again for the old tivo and try the lines. Also a technician is coming tomorrow. But I will call Directv again if it could have been a line problem that made the receiver freeze up.
