I'm about to give up. For weeks (maybe since the new HD channel rollout) we get constant audio dropouts and pixilation of our HD channels. When this problem is happening, the SD versions work just fine. It is not limited to one or two channels, but seems to happen on all HD to a greater or lesser extent. I've had to stop watching HD. My signal strength when we are having problems range from upper-80's to 100 on almost all transponders (other than those with zero or "N/A"). The exception is sat 103c. It's signals are upper-70's to mid-80's. We do have two transponders that are always down between 10 and 25, but I don't know if they are even used. These low signals are on sat 101 #28 and sat 99s #1. Customer service told me to tighten my cables (yeah right). DTV already charged me $19.95 (shipping) to replace my DVR (HR-20/700) that was under warranty. Now they want to charge me $79.95 to send out a tech to fix a problem with their service/equipment/installation. Basically they want to charge me even more, with no guarantees, to try and fix the programming I already pay over $100 per month for, but can't watch. Anyone have any suggestions or ideas? I don't want to go back to cable, but at least I would get my local channels in HD and the HD works.
