In terms of responsiveness of the slider, has anyone noticed a difference between movies playing in a browser window vs. playing in QuickTime player? (The movie is fully downloaded in both cases.) There's an instructor here that swears he sees a difference, finding the Player a better environment for his students to scrub around to closely examine the movie. I can't see it myself on my system. Just wondering if anybody out there can confirm or deny this instructor's experience... Judy Stern UC Berkeley
