DivX just released a plugin so you can watch DIVX encoded videos right in your browser.
Watching DivX videos just got (even) easier. The DivX Web Player is a sleek plug-in that allows DivX videos to be played directly within your web browser. The DivX Web Player offers webmasters, bloggers or absolutely anyone creating a web site (on MySpace, LiveJournal, etc.) a convenient tool for embedding high-quality DivX videos into their web pages. The DivX Web Player is included as part of the DivX Create and DivX Play downloads.
