Host ID not changing??

Technicians out again today. Now they think the reason my TIVO is not working is because the HOST ID is not changing?? They said when they insert new cards in the TIVO that the host ID is supposed to change each time. However, it remains the same. They said they could put a million cards in there but if the host id is not changing then it will never work??? However, when another technician (a week ago) noticed the number was not changing the pairing person on the phone told him that it was not supposed to change. It would remain the same. Have any of you heard of that? Is that number supposed to change? I'm beginning to think they will never figure out what is going on. They will not listen to me when I mention the conditional access menu and how the values must look. Anyway, I need to know if there is a possibility that they are on to something. Or if we will end up looking for another solution.......



ETA: My problem now is that I only have some of my channels. I'm missing a whole tier. I had all the channels for one night. Then the next morning a ton of channels were missing. The values have never added up. They are Con: YES, VAL: ? Auth: and FWK (something like that) a
