web page design with video

What kind of inexpensive software could I use to make a web page similar to the Videos page on TechRepublic or the YouTube site? I'm a business trainer, and I would like to have some way that my students/clients would be able to select and view short training videos.

The user might view the videos on the internet, an intranet or from a cd on their own pc.

Thanks in advance,
Pat B
