Advertisements I've searched around but haven't seen any posts with the same problem. Any help appreciated. Setup: -HR10-250 (installed 12/31), optical cable, McIntosh MX-132 receiver -Local channels through SAT, not OTA -Signal strength at 90s for 101 and 85 for 110 Problem: 1) Audio cuts out/blips out for 1-2 seconds and returns. -only noticed on Dolby 5.1 setting -Happens only on all the HD series of channels (HBO, HDNet, HDNet Movies, ABC, FOX, NBC, CBS, ESPN), though not necessarily HD broadcast (could be SD on HD channels) -Happens more frequently on ABC, FOX, NBC, CBS (10 times per hr?) -Happens on both live and recorded -On a live or recorded broadcast, does not blip out on the same spot, i.e., rewind and play and the audio is there 2) Crackling noise -Only on HD channels -ProLogic setting This doesn't happen as frequently so I haven't had time to do as much troubleshooting One other variable is that I had a Samsung SIR-TS360 (non-tivo) prior to this and it would also have audio cutouts (I never spent time troubleshooting it since it was hardly used). I have 3 other SD Tivos in other rooms and all are perfect. Similary the SD broadcast channels on the HR10-250 are also perfect. In both cases, video is perfect. Any ideas? Thanks!
