I recently swapped from my TivoHD to PremiereXL, and have had a heck of a time getting these folks at CinBellTel to get it working. They added a few HD channels a couple of months back, and those don't show up. Today, they added about 10 more and those aren't showing up as well. In fact the HDNet channels were moved and actually work in their new location.
According to their tech support folks, the card seems to be provisioned correctly. They have the right HostID, and CC info from the actual cablecard. (Different from the CC number on the Tivo diag screen.)
I also have HBO, and there was a provisioning problem with that as well. It now works, but the others still do not.
When I got the Premiere, I took the CC and put it in. With the exception of HBO and a few HD channels it worked fine. I don't know where else to what else to have them try. Any suggestions from CC experts out there?
