For those of you who might not know the difference:

• if you have a PC computer, you might want to use the Windows Media version.
• If you have an Apple Mac, Power PC or G-Anything, you probably want to use the QuickTime version.

If your computer responds with constant beeping, flashes the time or starts emitting harmful rays then you should probably not use either version - because you're probably sitting in front of your microwave. This also goes for VCRs, mad scientist equipment and 'Lite Brites.'
