Anyone have any idea what video file formats are supported by the tech carts in classrooms? I have a professor that used to use certain videos embedded in power point presentations a while back (and I don't know how far a while back was), but says at some point those carts were updated and his videos stopped working. So I'm trying to figure out a way to easily make it so he can continue to do this. It looks like the videos he has are Mpeg-2 files, so I'm not terribly surprised that they don't work. So I'd like to find an easy way to convert them to something that will work on the carts with as little loss in quality as possible. Any thoughts? Gary
