HR34 was installed Saturday. I moved some other DVRs around in the house. HR20 went from the living room to my office and the HR22 that was in my office went to my daughter's room (since it can do 3D and the HR20 cannot). All seemed fine until yesterday evening, while watching the Olympics, I lost signal on Tuner 1 on the HR20 for no apparent reason. The picture went from normal to frozen and I then got the lost signal message on Tuner 1. Doubleplay was being used and Tuner 2 was unaffected. The skies were clear so that was not an issue. I did a reboot and Tuner 1 was back. A bit later I had a few periods of signal breakup, I did not get a message of loss of signal but the video became very choppy for about 15 seconds (it was fine on another TV with the same show). I don't know what Tuner that choppiness occurred on but it was the same show where the Tuner actually went out on. I have no idea if the Tuner going out was related to the choppiness. Signal levels all looked good. All seems OK in the brief period I had it on this morning. Does this sound like a Tuner getting flakey or possibly another issue or simply an anomaly? I should mention that this is the same HR20 that had the issue of one Tuner (usually Tuner 1) not coming back online after a period of rainfade. That problem has not been an issue in some time but thought I should mention it.
