This is an excellent resource with a huge number of BB Code media sites. It is very configurable, allowing you to add just those you require as well as set the size of the videos if desired. The author works hard to maintain this add-on and constantly adds new media sites via requests. He is very helpful to users and has made several changes following requests. I would highly recommend this to anyone who wants more than the default BB Code media sites.
As everybody else have said. This add-on does what it says. I've seen my members amazed and felt happy by how things that can be embedded are by default embedded on their posts. Be it a pastebin snippet, a tweet on Twitter, or even a poll widget. Support from the author is also great. You can expect quick bug fix and continuous update. Totally recommended to install if you think that it's too much of a hassle to manually add more media sites to your XenForo installation.
Works and Works well. Although rarely utilized on my community it is nice that when you do come across a news story or video that isn't hosted on you tube that we can still easily embed just about any video with this plugin.. the Bonus is that the Author is updating the definitions on a regular basis.
