Millisecond Forums

Hello! 

I recently posted a study asking subjects to rate images of food and reactions after movies.

There are 6 videos, conditionally selected for .mp4 or .mwv format depending on Mac/Windows. I've received a number of emails saying that one of the videos (of Forrest Gump reuniting with his son) appears on the screen, then freezes, and am unsure what is wrong. There have been no complaints on the other videos. Any idea for why this might be happening? 

Thanks,
Karen
