Ditto....is there anybody out there who has success with fixing this Error 519? This started very recently and we can't watch old TV shows (e.g., Perry Mason) and perhaps some new ones also. I have installed the latest Adobe Flash PugIn on all of my usual browsers (both PC and iMacs) and we get the same errors....Anybody from Adobe has any answers please? Obviously the Comcast Support people are clueless!!
