Picked up some apple DVD-rs to burn an iDVD project. This is my second try, first was with no name cheap DVD-rs resulting in 2 coasters. The movie burned all the way through but only plays about half the movie before screen freeze up. I popped in an apple disc and hit burn, it is now 3 hours later and I'm on "stage 3 Asset encoding..." The movie was already compressed. Is it doing it again? Am I trapped in iDVD hell? Project is just under 4 gig. Any ideas? Thanks, I.
