I don't mind copying that info into the pixelation thread - I just don't want to look like a goofy cross-poster by doing that too much! From my experience, it was very clear that my TiVo S3 did not handle signal errors near as well as the Motorola STB. While this problem was going on, the affected channels would have various degrees of pixelation and freezing ever few minutes - programs completely ruined. But the STB would only show an occasional line, maybe once an hour. The key was to pay attention to both CORRECTED and the UNCORRECTED errors. Both S3 and STB showed HUGE numbers of corrected errors - something like 30,000 every 5 seconds. The S3 reported uncorrected errors down around 1,000, where the STB uncorrected number was more like 5 - that is why I so rarely saw the problems on their hardware. But they were still there. All of the channels on the unaffected frequencies consistently showed 0 Corrected and uncorrected errors. Strangely enough, none of the techs who worked on this problem even knew about the error count screen in their own diagnostics. Every time I had to teach it to one of them, they were surprised. BTW - as part of this troubleshooting, not only did they change the ONT 3 times (seems they could not believe it wasn't the problem, even though they could see signal errors on the line going into it!), but they ran a new coax straight from the ONT to the TiVo to prove that nothing in the house, such as bad coax or cheap splitters, was causing the problem. I think that running a new coax directly to one of the boxes is critical when "proving" to them that the error counts are in their signal! They eventually found bad equipment in the central office - had to wait for a maintenance window at 0darkthirty Sunday morning to bring system down and switch it out. Then everything cherry.
