I personally prefer the K-Lite Codec Pack over the Combined Community Codec Pack, as being much more evolved.
K-Lite also has as a separate download the K-Lite Codec Pack 64-bit: A bundle of 64-bit DirectShow filters that can be used together with 64-bit players, such as Windows Media Center.
[EDIT]
Please note that some blu-ray copy-protections work better with Windows Media Player
or with the software that was furnished with the disc.

These codecs and splitters should already be installed by your codec pack. If not, use another codec pack.
