For about the last year or so, whenever I watch a show or movie on FIOS, and the end credits roll, the typography "flutters". The type goes from being clear as a bell to a pixelated mess, and back. It doesn't matter what channel-EPIX, HBO, Cinemax, Starz, Showtime. It's maddening, and I can't find this issue online anywhere else.
I watched ep 2 of Ray Donavan season 3 last night, and as soon as the credits pop up, same issue. Tonight, I watched Capote, which I'd taped to my DVR a year ago when it played on EPIX. I don't notice it anywhere else within the movies or shows, but it's still an annoyance.
All the connections are tight. Subtitles are fine. Network diagnostic from the STB shows the signal is fine. I've reset the STB, and nothing works. The issue doesn't happen when watching content on HBO Go, or Showtime Anytime through my Roku, or anything from my Bluray player.
Suggestions? Is this an issue with the stream quality?
