1) it's illegal (contains lots of codecs it isn't allowed too)
2) (as if you need a second reason) there's a hell of a lot of duplicate codecs installed
3) you have NO CONTROL over your codecs at all. Joe Bloggs might not care, but if you even dabble in video editing to the extent of recompressing a single video in VirtualDub, then you'd regret installing K-Lite.
All I've got installed is:
- nVidia PureVideo (MPEG-2)
- FFDSHOW (H.264)
- Xvid (Xvid, DivX)
- Real and Quicktime Alternatives
- The codecs WMP installs itself
- And a couple of encoding codecs (LAME MP3 and AC3 Filter).
So much more in control. So much cleaner.
The alternative for people who can't be bothered or don't care is VLC media player. Free, and plays just about anything you throw at it, regardless of the installed codecs.
@Admiral Huddy: Gspot is a tool to identify video details - which video and audio codecs are required and provides info such as bitrates and things.
