X Codec Pack is a small codec pack.

Just the most used (popular) codecs are included (see below). If you are looking for a big pack with lots of codecs, filters, tools, this is the wrong place. Lots of codecs can mess up your Windows.

Unlike other codec packs, you can select the components you want to install, you get uninstall support, detection for previous installed versions, update for new versions - you don’t have to download the whole pack again.

With X Codec Pack you get :
DivX codec
XviD codec
GPL MPeG-1/2 decoder
AC3 filter
DivX AntiFreeze
DirectVobSub (VSFilter)
Video Inspector
Media Player Classic

All the codecs, filters, tools inside X Codec Pack are freeware.
