Well we're not releasing the raw WMV file. That's just for me and you. The rest get the 700MB avi for now but in December, I'll go back, fix the mistakes, render it as MPEG and then put it in the DVD with menus. I can honestly say I've learned much with this project as it's my first time tackling something so big.
From what I've seen with DVD Architect, it looks like it works similar to a website. I have experience with that so that shouldn't be a problem.
