I just bought the Hero 3 Black edition and my video playback it very choppy. Here are my computer specs: Macbook Pro 2.33GHz 2Gb of ram 256 Graphics card Lion 10.7.5 According to the gopro website, I should be able to handle the videos. However, so far, that has not been the case. I have tried playing the videos back in several different programs, and it's all the same. Even in gopro's own software after converting to .MOV, it is choppy. I have no problems streaming 1080 HD online.. Any ideas? I got this camera for my trip to Turks and Caicos and would really like to get the bugs worked out before i leave on the 15th.
