Multimedia Presentation

[swordfish1]

I am creating a presentation and was wondering if this was possible in PowerPoint 2007?

I have 2 separate PowerPoint presentations. The first has 50 photos that just fade between each other with audio in the background. I need this to run on a seamless loop before the actually presentation starts (Ex. 20 minutes prior to meeting).
I also have a similar presentation that I want to run later in the meeting. So - 2 separate presentations running independently in one.

Between these I need to display several videos and graphics and have them all seamlessly switch between each other.
Can this be done?
