Playing .WAV and MPEG files

I’m sure this is very simple, but these MACROMEDIA
tutorials are never clear. I want to play a .WAV file when a link
is clicked. How do I set this up on my page in DREAMWEAVER? Here is an
example site. [color=#800080][/color]

Also want to do the same with a movie file. I have movie clips from t.v.
commercials I’ve done and when a link is clicked I want a new smaller window
to open and play the clip. Either streaming or download. How/ where do I set
this up?

PLEASE HELP! I’m so close to being done …

Thanks much
