I have seen this sort of thing aswell. However, my very first box that I sent back and wish I had NOT, never did it. Each of the replacement boxes they have sent me have done this ;-(btmoore said:Another bug tonight.
At 9:00 the HR20 went to start recording Heroes on my local NBC station, while I was watching The Daily Show.
Right @ 9PM the message about signal loss popped up on the lower right screen, so I changed the channel to the local NBC station to see if that was the problem. For some reason it looked like the signal was lost so I quickly changed the channel to the west coast feed and started recording there. This meant I had 2 tuners in use, one on my recording and local trying to find a sat signal and the other recording the west coast NBC feed. I went back to my list and it showed 2 Heroes episodes being recorded with two different names being recorded.
I started playing my local one and it was a black screen and I still had the searching for signal message up. I went back into the list and had the DVR stop recording the local NBC station. It was still a black screen with the searching for signal message, so I changed the channel down one station, and boom I can watch that channel so I move back up to the local nbc station and boom it works perfectly. All this time the other tuner was engaged in recording the west coast feed. This means that for some reason this tuner or some where in the software or hardware chain associated to that tuner it failed to lock in to the station is was suppose to record. I don't know why but for some reason the HR20 thought it could not find the satellite once it tried to start the recording, but the dish and signal are fine and strong and, the transponders are strong with a clear sky tonight, and worked fine once I stopped the recording and forced the tuner to re-tune to that station. This is the second time I have seen this problem, where the HR20 has a problem locking in to the signal when trying to record, I am starting to wonder if this is not related to the unplayable recording problem.
