Well, I'd have to learn how to make different sizes first of all. I don't think I've done that before. :p It would probably be way faster/easier if you made a smaller version and stuck it in its own folder on the disc, or stick it on a separate CD, maybe?
I also kinda think that having a bunch of versions would sort of take away from the final, full menu/feature DVD, especially a high quality version. The one I'm being sent could be viewed as a test version for a pair of fresh eyes to see and comment on before the final, and I think it wouldn't be a bad idea if the one being distributed for now would be bare bones and smaller, like 700 MB or whatever. It would make the final version seem more...special. Know what I mean?
