I am having some serious problems with the Starbarians video. The audio in it is playing fine, but the video is jumping back and forth constantly, rendering it wholly unwatchable. Since I know I can't describe it accurately, I fired up CamStudio and recorded the first few seconds to show what I get in Firefox (with AdBlock) and Chrome (without AdBlock) when I try to watch it. Here it is (roughly 2.5MB).
Now, being the clever person that I am, I used Firefox to do some snooping and was able to download the mp4 file locally. When I play it here, both the audio and video are messed up. So I think it's the video file.
