I know Others seem to have this issue but mine seems different. Here is my issue. I have 2 hr24 units one is not hooked to a tv but i have swapped out the receivers and put the bedroom one on the main tv. I have a swm module connected. It seems to vary and it only comes or it seems to only come at random. Never seem to have drop outs on anything but locals. Such as right now im watching recorded law and order from local NBC station but i don't have ota hooked up so i assume that makes no difference. I have watched the whole show with only 1 audio drop out. Just earlier i was watching another show with audio drop outs at least 10-15 times in the hour long show as well as 2-3 vi doe drop outs and video blocking. It seems the audio is always there. As in i can rewind and the drop out in the same place. The video drop out however sometimes fixes itself on the rewind sometimes not. I have swapped out the receives and put the bedroom downstairs and it does the same thing. I took off the hdmi for audio and audio is now running through an optical cable. Did not change anything. Signal is good on all 3 satellites.
