For some reason (suddenly) I cannot get my Macbook Pro to play videos from my GoPro Hero 3. I'm recording 1080/24fps and I can open the video with either Quicktime or VLC and it will play the first half second then the screen freezes but the status bar continues to progress. Does anyone have any suggestions? My Macbook seems to be working properly, I haven't had any issues reading or editing videos from my P4 or my video camera (using FCPX). I'm stumped here.
