Quicktime Video playing in PowerPoint

I have set up a PowerPoint Presentation that has three quicktime movies that play during the presentation. In order to get them to play, I added them as a hyperlink as a webpage that directs it to the file on my desktop. The problem is that the presenter is using a wireless slider advancer to go through the presentation and when quicktime opens within PowerPoint it takes over control of the presentation and the slide advancer stops working. The only way to get to the next slide is by using the mouse to regain control and advance to the next slide. How can I fix this so that once the video is over quicktime relinquishes control back to PowerPoint so that the advancer begins to work again.

Oh and I did try to have the slide change automatically by setting the time of the slide and that does work, but the advancer stops working on the next slide and the same problem occurs.

Please help!!! I have to have this working seamlessly by Tuesday morning as the corporate sponsor and the owner will be there!!!

Thanks in Advance!!!!
