It can be difficult to keep up with the latest media encoding packs (codecs) but it is necessary to do so if you wish to continue to view certain media files. Fortunately, the “defilerpak” project keeps an eye on all of the latest codecs and puts them neatly in one package, the defilerpak. Download it at http://hellninjacommando.com/defilerpak/. Install and enjoy your MPEG’s!
