This plugin adds a shorttag for embedding MTV videos.
Use it like this: [mtv width=512 height=319]video-id[/mtv], where width and height are optional parameters. If you do not specify them, the values set in settings page are used.
Variable video-id can be found in the URL, for example:
http://www.mtv.com/videos/misc/516528/my-first-kiss-live.jhtml. That 516258 is video-id, which is needed to paste between [mtv] and [/mtv].
