I've tried everything.I even opened a NEW file with nothing on it and hit record. It's even jittery there. Most of the time it's sort of smooth. Other times it's almost as if the scroll line stumbles over the audio graphic and then catches up. I would think that if there's any streaming issue it would be noticed in the audio. Audio's perfect. As I said I'm not going to obsess on it. What's your thoughts on refresh rate. It's locked to 60Hz
