PowerPoint help

[Tomg]

I loaded a PP presentation to my Mogul (storage card), and the slides play, but the video's attached don't. I saved the videos on the storage card as well and they are there put they won't open. When I tap on one it displays an error mess. stating there is no application assoc. Run the the application first and then open the file from within. Some of the videos were not created in Windows media, so I think that is part of the problem. Can anyone advise what to try.

Thanks,
