Defiler has released the latest version of his DefilerPak over at his site, http://hellninjacommando.com/defilerpak/. You can access a direct download of the latest pak by clicking here and you can read the documentation on the project by clicking here.
For those of you unfamiliar with DefilerPak, it is a no-frills-attached package of the most commonly used audio and video codecís needed to watch or listen just about any media encoded in any current standard. The Pak is updated every time there is a significant release of a codec. I've used DefilerPak since version 1.09 and have never had a problem with a codec. Check it out, the power of waffles compels you!
