I am having the same problem: pixelation only on ABC on demand shows. For example, we try to watch The Goldbergs but its always pixelated right from the start. All other ABC on demand shows are the same way. No other load on our home network except for one desktop PC at the time pixelation happens. Other on demand channels are fine, though occasionally CBS shows are pixelated, but not as often as ABC. Is it an ABC issue, Fios issue? Since all other channels work fine, I doubt its a cable or other hardware issue. Any solution?
Not sure how much pixelation you were seeing.
I just started latest on demand episode of the goldbergs.
After a minute or so, no pixelation.
