K-Lite Codec Pack Mega

 The mega variant is the biggest of the four variants of the codec pack. It contains several additional components. Most importantly ACM/VFW codecs that can be used for video encoding/editing.
These codec packs are compatible with Windows XP, Vista, 2003, Windows 7, and Windows 8. The packs include 32-bit and 64-bit codecs, so they work great on both x86 and x64 variants of Windows!
