Wondering if anyone has any ideas..........playback is very choppy when viewing gopro footage, 720p-60 frames per second. When I make the window frame smaller it plays smooth, but when I want to watch it in full screen, it sucks unicorn dong. I have a MBP 13" 2011 8gb of ram. This is very dissapointing. 
Any help would be appreciated.......thank you all.
