Embedded videos (for example, from YouTube) can be placed into a page by using the following syntax:

{{#ev:servicename|vidID}}

Example:

http://www.youtube.com/user/argeedb?feature=mhw5#p/c/32375A246EDDB26A/0/G9R_aCgeexA

{{#ev:youtube|G9R_aCgeexA}}

In some urls the vidID may come directly before the first ? in the url.
