You should see a little QuickTime controller to the right of each
selection. If you don't, you should download
the free QuickTime standalone plug-in
for your browser from Apple. (Note: you do not need to register with
Apple to get the Quicktime download).
You may download these files for personal use only. To do so, right-click or control-click on the [Download] hyper-link and choose "Save target/link" or "Download target/link".
