Correct, if you are a member of EmuMovies, they offer the movies in AVI and FLV format. The AVI files you can use with pretty much any front end.
When I started with this hobby, I started using Maximus Arcade. I found that this front end was one of the easiest to configure. But I wasn't crazy about having to pay for it, and back then when this happened, it didn't have some of the features I was looking for (which have since been added).
After a while, I switched over to Mala. I love this front end. It's still very easy to configure in my opinion, and is highly customizable. Also, IMHO, I found the layout editor was much easier to use in Mala than the Maximus Arcade one was. So if you plan to make your own menus, this is something to consider.
I haven't played with hyperspin yet, so I can't comment on that front end, but at least from the little I've read, I didn't think it was that hard to configure...
