Outdated! Now, both K-Lite Codec Pack and K-Lite Mega Codec Pack have support for 64-bit.
K-Lite Codec Pack 64-bit
is a bundle of 64-bit DirectShow filters that can be used together with 64-bit players, such as Windows Media Center.
The 64-bit versions of Windows can run 32-bit software perfectly fine. So it is recommended to use the regular K-Lite Codec Pack when possible.
That one contains more, better and faster decoders. You only need 64-bit filters for use with 64-bit applications.
