The documentation (http://docs.moodle.org/en/Multimedia_plugins) says that to embed a youtube video within one page you have to surround the youtube URL with "[youtube]" tags. But it doesn't appear to work, at least in my installation.

It's not a big issue as you can embed the video using a plain "<a></a>" link (although in this case, surprisingly, the embedded multimedia player isn't used, instead, the youtube's one is).

To reproduce:

0) Make sure the multimedia plugin is enabled at site level amd the youtube filter is enabled too.
1) Add a "page" resource somewhere in a course.
2) Choose a youtube video and insert its link into the page enclosed within [youtube] tags as explained in the documentation.
3) Save and display. No video is embedded in the page. Instead, the "[youtube]link[youtube]" sentence is displayed as plain text.
