Which is the best forum or resource book for imovie/idvd?

Archived from groups: rec.video.desktop (More info?)

I enjoy imovie, but I have many technical questions I'd like to ask
fellow users, plus share what I have found useful. David Pogue's
'Missing Manual' is OK but dedicates too much space to basics, even of
camcorder use, instead of the many challenges that arise using
imovie/idvd. Is there a top-notch encyclopedia of imovie/idvd in
printed form? Better yet, since I am on the road, is there a
pay-per-question or by subscription forum staffed by experts where one
get into the nitty-gritty?
