No channels coming through
I just hooked up a new tiro premier in our bedroom, but I can not get any channels to come through. If I click the live TV button on the remote, a screen showing a progress bar and "scanning for channels" shows but never completes. It has been plugged in for a few days. I do have a M-card already installed in it that we picked up from the cable company (Cox).
They mentioned that I might need a decoder. I'll probably be callign them tomorrow, but I wanted to check here first to see if I'm missing something. I would have expected at least non-HD channels to come through, but I get nothing.
Note that if I hook up the cable straight to the TV, I do get all the normal non-HD channels that I used to get.
Thanks for any help.
