I have an HD cable box and lately, two of the HD channels go "zot" every 1-2 minutes and freeze for a moment.

This usually means the signal is too low. But the problem is only during prime time. I suppose that's when the most people are watching.

Why would it glitch every minute or so, and not all the time?

The problem is only on 707 (ABC, HD) or 713 (an indie station). It's not on 702 which is so popular.

I think the problem is not the box - that's my impression. (I'm near LA and have Charter cable.)

I can switch to the SD version of those channels if needed.

It is probably the individual cable run to that TV. Check the connectors on it to make sure they are making good contact. It could also be the cable itself. You could run a new cable.

Could be a bad cable. I had a herringbone type pattern on one channel. Neighborhood cable runs were in back yards. In my case, the cable ran from the cable box, under ground to the house. Cable tech guy had what looked like a metal detector and followed cable. Meter read a signal leak. He dug up a few feet of cable and found a small cut in the cable. Spliced in a repair section and problem solved.

The problem is two channels and only in prime time. That's why I thought it wasn't a physical cable problem.

That's what one would think, but I've seen weirder things happen. When you're not sure you have to work by process of elimination. I would try a temporary run of cable just to test.
