For a client project, they wanted a tabbed video player. The basics of it were pretty easy (and can be accomplished a number of ways) but I had a very hard time getting the videos to stop when I clicked on the next tab. Google eventually revealed the secret was to remove the SRC from the other IFRAMEs on click. Works for both YouTube and Vimeo embeds.
