WordPress' built-in oEmbed feature is fantastic. I've heard several complaints, though, about the related videos that show up after the video is done playing so I put together this very simple plugin that keeps the YouTube oEmbed code from showing related videos.
This plugin also adds wmode=transparent so that the flash object doesn't overlap a modal window.
On activation, the plugin clears the oEmbed cache so that the videos can be successfully re-cached with the new setting. If you are upgrading the plugin, you may need to manually deactivate, then reactivate it to clear the cache.
