HR20 with one tuner working - searching for satellite

[ONUOsFan]

I have the HR20 in my bedroom set up with only one line in, so it's only using one tuner (just no good way to get a second line in there) and it hasn't been a problem since I got it installed (a week and a half ago), but this morning I tried to tune to one of the new HD channels and got a searching for signal message.

After that, no matter what channel I tried to turn to, I just kept getting that message. I finally had to reset the box to get it back, and when it came back up it was on the channel I was on before I tried to change it.

I've never had this problem before, even while flipping around through the new channels yesterday, but I'm wondering if for some reason it tried to change to the second tuner and got stuck?

Anyone heard of this before and/or know if there's a way to keep it from happening again?

Anyone else using an HR20 with only one feed? Are you seeing this problem? I wasn't going to worry about it but it happened to me twice yesterday, and once was after I was watching TBS HD, turned off the box, then turned it back on. So it was tuned in fine and then wasn't, without me changing any channels.

I'm just trying to figure out if there is a way I can fix or get around this without running another line...
