only thing I can add to that is that idvd only does dvd-r's and dvd-rw's. That is of course with an internal burner. An external burner may be able to do dvd+r's but it won't be able to do anything else. It's weird I know. Toast is the best software consumer-wise that I've used for my mac. The only thing I don't like about it is that you can't create dvd menus for your disks. This is a feature that I like about idvd. Now if you were to get DVD Studio Pro, which is about 400 bucks, you wouldn't have to deal with any of that stuff.
