Our videos are available in both Flash streaming and downloadable versions.

To view the Flash version, you need to have the Adobe Flash Player version 10.2 or higher plugin for your web browser.

It can be downloaded for free from Adobe.

The Flash videos are available in four sizes (two for older, non-HD videos).

In order to view the streaming Flash videos smoothly, you must be able to maintain a steady connection to our server that is equal to or greater than the bits per second required to view the video.

If you cannot get smooth playback, you should try a smaller version of the video, or download it first and play it in a standalone player.

The downloadable videos are available in MPEG-4 AVC (.mp4) format in 1280x720 (for HD videos), 854x480 (for HD videos), 640x360 (640x480 for non-HD) and 480x272 (368x272 for non-HD).

To download a video, right-click on the link and select "save target as..." (Internet Explorer) or "save link as..." (Firefox).

The 1280x720 size is targeted for the iPad and notebook and desktop computers.

The 854x480 size is targeted for computers and high-end smart phones.

The 640x360 size is targeted for smart phones, iPod Touch, and similar devices.

The 480x272 size is targeted for the PSP handheld game console.

All of these files will play on a computer using various standalone video players.

The 1280x720 size requires an efficient player. Unfortunately, most Windows PCs have Quicktime Player on them, and it wants to play every .mp4 file, even though its performance under Windows is terrible.

On Windows 7, the included Windows Media Player is probably the best player for the 1280x720 MP4 videos.

For other Windows versions, we recommend the free VLC Player. It is available from

On the Mac, Quicktime player performs very well and is fine to use.

For the smaller sizes, it isn't so important which player you use.

For the older SD videos, we also have a 640x480 Windows Media 9 (.wmv) version.

It requires Windows Media Player 10 or higher.

For Windows, it is available from

On the Mac, we recommend Microsoft's wmv plugin for Quicktime.

There are also MPEG-1 files in lower resolution. This is a very old format, and almost every player should play them properly.

We also have a few very old videos available in DivX (.avi) format.

VLC Player (see above for MP4) will play them. There is also a free player from the creators of DivX
