Gentlemen,
Thank you both for the information. I appreciate the help.
I've been using the regular 24p mode for nearly all of my projects, but I didn't want to be missing out if the advanced mode looked a lot better. The way I read it, unless I'm doing a film out or need to print out each frame, I don't really need the advanced mode.
Peter, thank you for the Adam Wilt link (very informative!) and Dave, thanks for your perspective and congratulations on your first true 24p DVD.
The 450 really is a great camera, period.
