Hey! Welcome to JustAnswer! I'll be happy to help you with this.
There is no on-board application on the iPad that runs PowerPoint
presentations, but there are third-party tools that can accomplish this. In my experience, by far the best one is called SlideShark. SlideShark, remarkably, is a free program. You can find it on iTunes here:
It has the built-in ability to play WMV and AVI videos that are embedded in the presentation. Chances are your videos are in these formats, but if they aren't, I can help you convert them.Keynote
is a fabulous program, but it does require rebuilding your presentation from scratch. In my experience, it's a bit more complicated to use than PowerPoint, but it's also a bit more powerful. If you already have your presentation, though, I highly recommend SlideShark.
