The codec packs contains a Settings Application to use in conjunction with your windows media center setup which will enable each user to choose different splitters and decoders for specific filetypes. The software will also allow you to choose from 10 different speaker configurations from 'same as input' and all the way up to full 7.1 channel output.

Do you want to watch your favorite video in MediaCenter? These components are tested on x64. This release is fully compatible with the 32bit codecs installed by the Vista Codec Package. It is fully uninstallable through the Windows interface.

Vista Ultimate x64 uses the 32bit player as the system default. The installed components of this release include icons to allow you to change the system's default player between the 32bit and 64bit Windows Media Player.

Observation to be noted
One other aspect of Vista x64 Windows Media Player(s) needs to be mentioned. If you associate a particular filetype to open with WMP while the system default is set to use the 64bit player, that filetype will always open the 64bit player when doubleclicked. This occurs even if you change the system default back to using the 32bit player. (and vice-versa)

The 32bit player has better codec support at this time provided by the Vista Codec Package.

On my system, I set the 64bit Player as default and use Media Player Classic (MPC) for files the 64bit player's can't handle. Since MediaCenter uses Windows Media Players' playlist for its own library, I found this to be the best setup.

This release is a fully functional standalone installation which may be included in an unattended environment using the switch -ai and is 100% compatible with the 32bit codecs installed by the Vista Codec Package.
