Help. I'm having some severe pixellation problems on a few channels that have just popped up on my two S3 OLEDs. I have TWC in Northeast Wisconsin with two M-cablecards and a Cisco TA on each S3. I've been running this setup for over a year now with very few problems. The gist of the issue is this: I have at least 3 HD channels that have the picture breaking up quite badly. Unfortunately, one of them is ESPN which I watch frequently. The same 3 channels are effected on both Tivos, and I've verified that the channels are non-SDV. They also all share the same frequency - 525MHz. The DVR Diagnostics screen shows that these channels only have a Signal strength of about 55, whereas all other channels are between 90-100. This pixellation issue exists on both tuners and both Cablecards, and also still happens even when I remove one of the cablecards. For troubleshooting, I have removed the TA and all splitters/amplifiers and connected one of the Tivos directly to the incoming cable feed, and the issue persisted. I also tried it with just the amplifier and oddly enough the signal strength on those channels was exactly the same whether the amplifier was in line or not. I know the amp is working, though, because the signal levels on all of my other channels drops when I remove the amp. So, can anyone tell me why this problem only effects the 525MHz frequency, and why the amp seems to have no effect on that frequency? For some further info - this issue just popped up this week after a TWC tech was here to swap out one of their crappy SA8300 DVRs with a new one. I believe the guy might have monkeyed with my wiring (for no reason whatsoever) where my amp and distribution splitters are. But I can't seem to "un-monkey" it no matter what I do with those splitters and amp. I believe he even went so far as to cut off the connectors and re-terminate some new ones on some of my cables. Is it possible for a bad cable connection to affect just this one frequency? What am I missing here? What else can I check? I have a TWC tech scheduled to come back this weekend, and I'd like to be able to suggest a solution for him before he further screws things up.
