For a while now I have been noticing glitches in DVR recordings as well as when I'm watching TV through the buffer (rewound at some point and not caught up to live TV yet). The video & audio drops out for a second somewhere in the recording, occasionally longer but I can't usually tell for just how long. This has been happening on BOTH HR24's. I had a service call and the tech said my signal strengths were low and ended up replacing the dish and aligning it. Signal strengths were great after that, but the problem persists. A 2nd tech came out supposedly to "check the resistance in the cable runs" but did nothing after seeing the strong signal strengths. (He visually inspected a couple of the cables where they connect to the receivers) He believes that both HR24's are failing and need to be replaced. However, I find this to be HIGHLY unlikely because I recorded the same program at the same time on both DVRs the other night, and both recordings had the glitch in the EXACT same spot. Other important info: - Both DVRs have been down to under 20% free space a couple times but are currently both over 60%. - This happens even when the weather is perfectly clear. - Signal strengths are all strong as a result of the dish replacement/alignment. - Not sure if the dish type shown in my signature is accurate anymore (as a result of the first service call) Any ideas as to what can be causing this? D* tech support says perhaps the multiswitch and/or the SWM. I have another tech coming out on Tuesday. I don't mind them swapping out the DVRs as long as they have other HR24s on the truck, but I doubt it will solve the problem.
