Create Custom Titles and Credits in Windows Movie Maker
This one requires some coding knowledge or at least the ability to read and write XML, but it's one of the more useful hacks I've seen for Windows Movie Maker. Among many gripes about the current version is a lack of custom settings to configure your own Title and Credits settings. You're either stuck with the defaults or need to hack together your own title screens using a photo editing application, like I did for the Steven Page video. Apparently there's a way to make your own titles and credits, Microsoft just never documented it in the API. Awhile back Rehan Ahmad documented this trick on his rehanfx site, complete with a number of examples and all the specifics you need to make custom titles.
