I have 6 HD DVRs and one HD STB set up on my system. Most of the DVRS are HR20-100's with a couple of HR21-700's thrown in for good measure. For the past year or more I've been having trouble with (mainly) my HD LIL channels, particularly fox but also abc (I'm in Houston). The SD channels are fine, but I get almost constant break ups and freezing on the HD channels (my wife is going to kill me as she likes 24, Idol and So You Think You Can Dance :nono. It is most noticeable, I believe, when more than one DVR is recording, but is still a problem even if I cancel the other DVRs and just record on one. This also occurs if watching live. I don't have problems on any other channel other than 296 and 299 HD kids channels, which sometimes just black out and give me a searching for satellite message. This doesn't happen very often, though. My signal strength is in the mid to high 90's on all satellites, and doesn't swing, so signal strenght doesn't appear to be the issues. I've replaced all of my BBC's, reset, reset and reset some more. I'm running out of options, Directv doesn't seem interested in helping, and I've still got the wife is going to kill me issue. Any thoughts?
