PocketMatrix

(Sorry, this is a Desktop question) I am working on a powerpoint presentation and I noticed that PP has VB built into it. I would like to use VB to run a Windows Media video during the powerpoint. This means that I want to build it right into the slideshow. How can I go about doing this?? I found the MP control in my computer, but Im not sure how to use it. I dont really know how to get it to play a file?!?!

THANKS FOR ANY HELP!
