What is the difference between the downloaded videos and the DVDs?
The only difference is the compression technology used to deliever the content. DVD’s use a codec called MPEG-2 and the downloadable videos use Apple’s H.264 codec. In terms of image quality there is virtually no difference between the two. H.264 is the standard codec used to encode high definition video delievered on HD-DVD and Blu-Ray disc. The only requirement to play the downloads is the free Apple Quick Time Player or the VLC Player. We reccomend using the VLC Player for smooth playback experience and Quicktime for video quality. The QuickTime Player tends to have slower playback which has not been adressed in version 7.4.
