Just a tip I found out playing around with mpeg streamclip. I complained before about the jaggies. So I tried deinterlacing and found out it reduces them pretty good. Not total but a good amount.
Another tip for users of iMovie. Did some searches on plugins (didn't know they made any for iMovie) and found a great site for plugins. Its for iMovie 6 and below. Apple disabled this feature for iMovie 8. Anyway, go to
http://www.geethree.com/index.html . If I would have know about these, I would not have purchased final cut express as I am still trying to figure FCE out.
Just thought I would pass this on to those who did not know about this.

PS. For those who got iMovie 8 with your new mac and did not like it, you can download iMove 6 for free from apple.
