So I was looking forward to getting my mac in time to do some presentations for school and wanted to make them really snazzy. Then, when I got it on Friday, I realized I had not clue how to use it. I'm doing a presentation on my travels for a spanish class and have learned now that i can use "iMovie" to make animated maps, add video clips, and have a photo slide show. This is perfect, but will I be able to open it at school using the PC's they have? I could burn it to a DVD but I'm not sure if they have DVD-ROM's in the classroom. Will it save in a file format that opens in windows? or can i convert it using a DVD converter type software and if so, which one is good? Popcorn(I want to start making DVD's from my torrent files too, do I need an outside app or will something in iLife work)? As you can tell I know nothing about computers, so I put all faith in your advice. Thanks you very much.
