Exactly what does the CCCP install and why?

CCCP Start Menu Group, All Options Installed
The current playback pack will install:
* Haali Media Splitter 2005-11-25.2 (MKV,MP4,OGM,AVI)
o Required for compliant MKV playback. Attempts to disable other MKV splitters on the system. This filter is also used for MP4 and OGM, as well as AVI. AVI is not used by default in the pack and is not recommended to do so. You will, however, need the OGM and MP4 parts for playing those files, as Windows doesn't understand those formats by itself.
* VSFilter 2.37 (SSA/ASS,SRT,VOBSUB Subtitles)
o Displays subtitles. It will attempt to disable any previous DirectVobSub installations you might have.
* ffdshow 2005-12-20 CCCP build (H.264/AVC,DivX,XviD, various audio formats etc.)
o Decodes H.264, XviD, DivX, and generic MPEG-4 video. Also used for audio decoding with the following formats turned on by default: AAC, Vorbis, MP3, AC3, DTS, FLAC, TTA. If you would like to turn off ffdshow decoding for a specific video or audio format, read further down for instructions on how to do it properly. Note: this is a stripped-down and well tested ffdshow build. Do NOT assume that you can replace it with any other ffdshow version.
* WMV9VCM
o Required to play wmv9 content if you don't have Windows Media Player 9 or 10 or Windows Media Format SDK or Microsoft Codec Installation Package for Windows Media Player 7.1 installed - ffdshow can't decode wmv9. If any of those are installed, then wmv9vcm will be ignored during playback (even if it was installed by CCCP) and the wmv9 codecs that come with them will be used instead (which is a good thing).
* Media Player Classic 6.4.8.7
o Media Player Classic, one of the two recommended players. Choose this one or Zoom Player according to your preference.
* Zoom Player Standard 4.51
o The other recommended player. Other players are NOT supported; see the Media Players page.
