I've noticed for the past week or so on Golf Channel HD 218 video noise which can be seen clearly against a dark background. It's in the form of white sparkles. First saw it when watching the Singapore tournament last week and thought it was that satellite feed but now I see it on all programming. Don't know if its coming from golf channel uplink or Directv. You can also hear audio noise if you have a good home theater setup. Anybody else noticed this?
