I'm having a bit of an unusual issue. I noticed seemingly random pixelation on FoodHD (854 on Comcast Boston/Brookline) for several months and finally investigated. Other channels seem fine. From DVR diag: Signal level is 98-99% with SNR 39dB Some RS uncorrected errors on this channel only (241149 in 8 hours) Lots of RS corrected on this channel only (3004420 in 8 hours) Equipment: Roamio Pro Motorola SB6121 cable modem 2-way splitter to cable modem/Roamio Pro The interesting part is that running a speedtest causes the uncorrected errors to sky rocket during the upload phase of the test. This also instantly causes terrible pixelation. I get 3260 uncorrected and 4986 corrected errors during a single speedtest, all uncorrected and the vast majority (99%) of corrected errors occurring during upload. I suspect that the seemingly random pixelation I've been getting coincides with random upload bursts from the various computers and other internet connected devices in the house. Even without the speedtest involved, I get some uncorrected errors on this channel, but 0 on others that I checked. Doesn't seem to matter which tuner is used. I did get random pixelation on the same channel with my old Premiere XL4, but it seemed much less common. I never tested the upload thing since I just stumbled upon that last night. Any ideas what might be going on here? Anything else I should check?
