Advertisements With the problem affecting so many users, I'm astounded that the problem has not been authoritatively identified and solved. I see pixelation on some of my fios channels, and I believe I've narrowed it down to only channels in the higher frequency ranges, nearing the high end. That is, from about 550,000-690,000. Most of the pixelating channels are in that 690,000 frequency batch. Signal levels are generally in the 85 range, with snr of 34-37, with most channels, including pixelating channels. However, sometimes I see that the signal level drops to 68, and bounces between 68 and 85. I don't know why I'm not getting nearer 100, but I don't think that's the problem. That said, I'd think a diplexer blocking all frequencies over 860 would work, IF the problem is in fact bleed over from the moca set up used in the fios system. On the other hand, if the problem is in cablecards, the diplexer will obviously have little or no effect. I've only just received the cablecards, and the installer tech mentioned that he had to search long and hard to find them (2 s-cards for each of 3 tivos). Apparently they're in short supply in my area (Philly suburbs)? I'm actually hoping the problem is with the cards, and that simply swapping them out will work. Even better, if I could get m-cards instead, that would be best, just for cutting costs. I never saw the problem with my motorola 6416s. So what's the deal? Bottom line is, is there a definitive statement of the problem?
