I have been recording HBO and SHO using the pany combo for about two years now without any problems. For a week now, I have been having video and audio breakups on the HD channels on my dish 5000. They randomly come and go, at times just a minor breakup at other times it is so constant that it is unwatchable. My dish pointing signal strength is around 90. The SD channels seem to be ok. Is anyone else seeing this??? Since no other threads have asked this question, I assume it is in my equipment. Has anyone had a failure like this? Any ideas on what to check? I just hope it isn't the modulator!
