Anyone have any luck burning DVDs using iDVD with an external burner? I bought a Powerbook a few months back. My first Mac purchase. I bought the Powerbook for security reasons and didn't see a need to buy a Superdrive. It wasn't until later that I realized how great it is for storing and editing media. I came across an easter egg that's supposed to help my Powerbook identify an external DVD burner. I just bought a Firewire enclosure for my internal DVD burner that I recently bought for my PC. Would be interested in hearing experiences people have had with using an external burner and iDVD, good or bad. Hopefully there will be more good experiences than bad...
