I'm not a computer expert by any means but am looking to edit an MPEG video that I have. I recently decided to switch from a PC to a Mac, but didn't think it was wise to invest in a new one and then possibly not like it, so I got an iBook G4 first---it's pretty good and has a good amount of space and Leopard installed on it, but alas, since it's not new, no iLife. Therein lies the problem. I was relatively computer illiterate on my PC, so I'm even more so with my new Mac. Hopefully you guys can help.

I am looking to do something very, very basic with an MPEG clip: insert a slide (i.e., a powerpoint string text slide, just a slide with some words on it) before the video starts. When I used Windows Movie Maker, it was a snap: just insert a transition before the video, finish it, and save it, and then it became part of the video. Great. I'm pretty sure iMovie could do something like that, but I don't have it (and I'm not even sure if iMovie would support MPEG w/out another codec of some sort). I tried downloading a few programs (Jahshaka, HyperEngine AV), etc, but they were ridiculously complicated for my expertise (or lackthereof). Does anyone know of a relatively intuitive, simple, free program that I can use on Leopard to just load the MPEG video, put a transition slide at the beginning, and then combine them to make a video?

Any help or advice would be much appreciated. Thanks!
