I've seen a couple of posts about this message before but nothing quite the same. On my HR20-100 I went to check my signal strengths and got the message " The process you have requested conflicts with the following scheduled events: Signal Testing" so I decided not to interrupt. I exited and continued to watch the channel I had been on. Later I went back to check signal strength and discovered none of my signal meters would get a reading. All available transponders on every satellite stayed showing the -- , not zero. When I looked at an individual transponder I got the "not acquired" message for both tuners, even though both tuners continued to receive the selected channels fine when I exited from test. I didn't have time to investigate so I exited. The HR20 has continued to record correctly for the last two days, no problems. So today I go to check the signal strength and get the message "The process you have requested conflicts with the following scheduled events" and then a blank line - no scheduled event, not even "signal testing". When I decided to interrupt, I was returned to the menu with " check signal strength" again, and if I selected that, back to the "conflict" message. I exited completely from the setup menu, came in again and selected to check signal strength. This time I did not get the "conflict" message, but got all available transponders with -- again. I decided to do a reset and that cleared the problem - this is the first unscheduled reset I have done on my HR20-100 since I received it in June. And everything else was still working, it was just the signal strength metering that stopped working. Does anyone know exactly what the "signal testing" event is??
