Why is QuickTime 7 required to view some videos in the Online Training Library®?
As of January 1, 2008, new videos are being published in a format (H.264) that requires QuickTime version 7.0 or higher. Previously, QuickTime 6 would have sufficed, although version 7.0.4 or higher has always been required to view movies with closed captioning.
