Has anyone been having macroblocking problems on HD channnels with Comcast. For the last month or so I have been having problems with HBO-HD, NESN-HD, TNT-HD, and a few others in the 83X range. I was using a Motorola DCT3416 HD-DVR. Sometimes I would get no picture or audio on HBO-HD. I am using a Panamax MX5300 surge protector/line conditioner and run the coax from the wall to the panamax then out to the DCT3416. I have been using this setup since February with no problems until a few weeks ago when the macroblocking showed up. I checked all my connections and they were fine. I finally broke down and went down to the local Comcast office and swapped my old box for a brand new Motorola DCH3416. This made no difference. Last night I decided to troubleshoot the connections. I also tried running the coax to my old Monster surge protector/line conditioner and had similar results. After awhile, I found that it was running the coax to the Panamax that was causing the problem. When I ran the coax straight to the cable box, everything worked fine. Why after 5 months do the line conditioners not work? Is Comcast doing something with the signal? I called Comcast this morning and they said that I shouldn't run the coax to the line conditioner. Anyone else having this problem?
