Hi, Brad. The movies are all Windows Media Video. I used to be a Mac guy myself and I know there's software that allows you to view them, so I recommend you do a quick search to see what's needed. Here's a link to a WMV movie; download it and see if you can watch it.

I hope you can figure something out!
