Macroblocking and pixelation with Tivo Bolt-- Comcast visit made it worse
All of a sudden we started getting macroblocking on most of the 700 series HD channels, except MSNBC and CNN. We had a Comcast tech out yesterday who said our signal was weak and he proceeded to change out our 9 position splitter (we're in an apartment building and inherited this) with a 2 position and he also made some sort of adjustment at the wall junction.
Once he did this, all of the 700 series channels went out and as he fiddled around, we lost more and more channels. He went and put a filter on the line somewhere at the source, not our apartment. He then decided it was the cable card in the cable box and switched that out. At that point we stopped getting ANY channels at all. He then told us our Tivo box was broken and there was nothing more he could do. He spent 7 hours on this!!!
We've done all the Tivo diagnostics and we do NOT have a signal lock (originally before he came, we did), our RS uncorrected is in the millions! before he came it was around 27K; our SNR is 15dB before he came it still was only 26dB.
All connections, cables, etc. have been checked. I've convinced Comcast they need to come out again tomorrow because *they* broke it. We're thinking perhaps the new Cable Card/M card isn't paired correctly?
Any ideas? How do we convince Comcast it isn't the Tivo and make them fix what they made even worse?
