so where are you.
Pacific Northwest.
And now that you've mentioned it, it only happens on H2H. But then again, that's all I use the receiver for other than moving the dish for my OpenBox. My LNB runs into my OpenBox 1st, then from there to my 4D unit. I probably won't be watching much TV this weekend but next time I plan on watching for a couple hours of H2H, I may run the LNB directly to the 4D unit. There could be some issue with the OpenBox.
