The signal goes berserk when I lower signal values. But in all of my tryouts, the moment I increase the signal levels everything seems to go back to normal. The only times it doesn't, I don't have enough data passing through the tuner and I see occasional errors but in a very low rate, which makes me think that a lot of data is not being passed through the tuner. But some is, error rate is not enough to trigger a reset and I don't get any "no DVR output". In those cases a simple process restart is sufficient to put everything back to normal.</span></div><div><span style="font-size:12.8px"><br></span></div><div><span style="font-size:12.8px">Now, in this case, not even a process restart is enough.</span></div><div><span style="font-size:12.8px"><br></span></div><div><span style="font-size:12.8px">I don't understand exactly how CAMs works in the frontend level, but could it be that this CAM, in this situation is blocking the TS data for some reason?
