Codecs have always been a tricky thing to get right but this package takes from the best, all the big name creators and several small ones too. All possible conflicts have already been dealt with.
Note this program does not contain a media player and it does not associates filetypes. With this package installed you will be able to use any media player (limited by the players capabilities) to play DVD's, movies and video clips such as quicktime, realmedia, avi, mpeg, Flv, swf, wmv, etc.
Streaming video is supported in most web browsers. By default you shouldn't need to make any adjustments to enjoy your media content immediately.
