I have done a search, and seen that some have had some issues with shows on NBC, Chuck, Heroes, and Journeyman. Of the three, I only watch Journeyman, and until this week, had been four episodes behind. I watched all four episodes over the last three days, but three of the four had periods of a minute or more of being completely unwatchable. In fact, there was one episode that I probably missed ten minutes due to the pixelation/macroblocking issues. Not reeally sure how to describe it, but I lose both audio and video during these times. So is there any idea yet as to what is causing these problems? Is this a network issue, a DIRECTV issue, an HR20 issue? Whatever it is, it needs to be fixed, and it only seems to be a problem for me with Journeyman, even though I watch several other NBC shows without issue.
