HELP!
These
movies are designed to "stream". This means that playback
will begin automatically when enough of the file has been downloaded
such that playback can be completed without overtaking the download.
If you experience sound but no picture, please wait for the stream to
complete, then close your browser and try again. The movie should then
play correctly from your browser cache.
If you are still having difficulty, click here
to check your QuickTime installation to establish if it is correctly
set up for video streaming.

If, after all this, you are still having difficulties with these movies,
please advise the Webmaster
