HR20-700
Anyone had this problem? Local HD channels are received fine EXCEPT when I record on one of these channels, all of the other locals go "771". I find that tuner 1 is off. I stop the recording and all locals come back and both tuners are at full steam. I switch cables and the same thing happens, but this time tuner 2 is off. This not only affects the locals but a few other "771" channels. Someone suggested I switch the BBC modules to see if that would make any difference. I haven't tried that yet. I ordered 2 free BBC's from DTV. BTW, all of my alternate (non-HD) are available and and have no affect on the recording or tuners.

I appear to be having the same issue. The tech said I needed a service call, which I don't think is the issue.

Anyone else experiencing this?

You do need to swap the BBC’s to know for sure, but my guess is that one of them is bad. If the problem stays with the incoming coax and not the BBC, then I’d suspect a multiswitch problem.

I posted on another thread that the tech brought in a new hr22nc but after going up on the roof he comes in and tells me the problem was a bad diplexer. So, my hr20 is now working fine.
