Literal [XP]:
Apple has made available a preview release of QuickTime 7 Player and QuickTime 7 Pro for Windows, the industry’s first mainstream H.264 solution for streaming and playback of High Definition (HD) video on the Windows platform. Ratified as part of the MPEG-4 standard, the H.264 video codec delivers high quality video across a broad range of bandwidths, from 3G for mobile devices to iChat AV for video conferencing to HD for broadcast and DVD. H.264 has been adopted by both the DVD Forum and Blu-ray Disc Association for the next generation of high-definition DVDs.
