I've been working on a film on imovie for over 3 months, and now that I've exported it to idvd and burned it onto a disc, when I put it in my dvd player it skips around and acts as if the disc is scratched (I know it's not because they are brand new dvd-r discs). Our dvd player works perfectly fine with other DVDs, and I'm planning on sending this film to a group of friends. I don't know if my dvd problems have to do with how big the file is or something. I have room to experiment because we bought a 100 pack of dvd-r discs, so anything you might suggest, I am thankful for.
