I was quoting the second Rogers tech who solved the problem. The first guy
said it was the filter on the curb box. The second guy solved it by having
the last few feet replaced.

He was lamenting that the Cisco 4642 HD have a low tolerance to signal
issues, and that is why some channels will not show up properly.
