I am new with the mark 2. I love the camera and the stills I produce with it. I also love the notion of HD video and been experimenting for two weeks now. Great quality one problem.
I video playback using quicktime (Apple) is somewhat jerky..not a lot yet not a smooth playback any suggestions? Thank you

Here is a good solution:

5D Mark II video playback|PHOTOGRAPHY WITHIN (http://www.theis.dk/blog/index.php/17/01/2009/5d-mark-ii-video-playback/)

Followed your response..works like a charm..Thank you.
Also can I edit the files with Vegas platinum?
