I've been getting Chicago HD stations after I "moved" there. I was gone for a couple of weeks and have a bunch of shows recorded on the 622. It seems though that for every single show recorded on ABC there's a lot of heavy pixelation from time to time (sounds continues normal, but the pic gets green and pixelated for like 3-5 seconds). Anybody else experiencing that? COuld it be week signal from 129 or something from the ABC station in chicago or even the national feed?
