Now this is
pretty cool: Apple has posted a series of eight video podcasts to the iTunes Music Store [link] that explain how to make a
great podcast (both audio and video) with iLife '06. Topics include setting recording levels in GarageBand, making use of introductory music and sound effects,
adding web links and images and editing video with iMovie HD.
Check out these video tutorials, they contain some useful information.
