Video Format! Which one to use? The three biggies are AVI, MPEG, and Quicktime (mov). Many people haven't configured their computer to play all three. But if you have to pick, I would suggest AVI (Audio Video Interlaced) as all Windows based machines are already set to play the file format. If you have a Mac, try the Quicktime (http://www.apple.com/quicktime/download/) or the MPEG.
