I am working on making a presenation CD for someone. I was given four powerpoint presenations with sound recorded in it. I have to make this presenation in Flash.

After the intro movie and all we will go to a frame with four buttons each leading to a different pps file. What do i need to do so that these pps file do not open up in a browser, if I do get URL they will open up in the default browser. The files already being a slide show I dont want them to open in a browser.

Can anyone help me out??
