I have a presentation in class tomorrow (he just told us today that we can use powerpoint, so ya), and I wanted to have a movie in there. I will be doing the entire presentation on my Windows based PC, and then viewing it on a Mac...I'm not sure what exactly it is, but its some type of I-Book.....I'm wondering if I would have to convert my video compression format....Right now, I have it in DivX....I'm wondering if the Mac would read that format, or if I would have to convert it to something like Quicktime...Thx in advance.
