The samples are in QuickTime, Windows Media, and Flash video. With a dial-up connection use the low bandwidth links of each format, with broadband (DSL or Cable) use the medium, and with a fast broadband connection (high-speed DSL, cable, T1 or higher) use the high bandwidth links. To view the QuickTime samples you need QuickTime 7 or higher. Download the QuickTime plug-in for Windows from here or for the Mac from here. If you are interested in viewing the samples at their highest online quality we recommend viewing them in QuickTime, even if you are on a Windows PC, because the H264 codec that QuickTime 7 uses is the most efficient codec for online viewing and streaming.
