||I'm trying something out with the Flash video. By default, the buffer time is set to .1 seconds, which it seems starts the video up right away if you have the speed for it. I changed it to 15 seconds, so that the video won't start playing until you've received the first 15 seconds and I'd like to see if it helps with the choppiness some people have reported.
Keep in mind, this was a change to the .swf that loads the video content, not the content itself, so you may have clear your browser cache to get the new file.
Let me know if you notice any difference.
