For many people who have trouble playing some videos or music, this should solve all of those problems once and for all. PCs come with a very short list of built-in video codecs so you will often run into trouble playing movies you get from friends or on the Internet. This pack will correct the playback of any video or audio files that give you error messages. For the power user who wants more than just playback this pack also includes a good set of filters and tools such as codec tweak, mediainfo, graphstudio and bitrate calculator.
