Microsoft User Network Decoder Pack for Windows Media encoding PCs This is a Decoder Pack not a
codec pack. If you do DivX,
xvid or 3ivX encoding this decoder pack is not for you. It is targetted for Windows Media encoding PCs.
Although this decoder pack can co-exist with other
codec packs, it is strongly recommended to Uninstall all other
codec packs before continuing. If you still can play DivX,
xvid or 3ivX files using your DirectShow player after uninstalling other
codec packs, this means that the codecs are not properly unregistered. If this is the case you will have to manually unregister these codecs. If you are not sure how to do so visit http://microsoftusernetwork.com/forum.
