Video and sound clips for powerpoint business presentations?

[TUS 373]

The more mature PH readership will probably remember training room gems such as the business videos made by John Cleese and his Video Arts company.

Now, I am trying to put together some good training materials that I can incorporate into powerpoint presentations for the nect generation of UK's captains of industry. Can anyone suggest any websites where I can download freely available sound and video clips of material that would be of interest please?
