It seems though you are trying to make the argument that iMovie 08 is less capable than 06. I would like to know why you think this. Yes the timeline is gone, but can you not still edit clips into a movie, add effects and transitions and such?
I’m with Kate on this one. The timeline is gone and that means the multiple audio tracks are gone. Using iMovie 8, try to add background music as an additional track to the movie. You could do it in iMovie 6.
One other thing-- iMovie 8 breaks a bunch of the iMovie plugins for text, effects, and transitions. So, if you had such in older movies, and go to edit them in iMovie 8, they’re broken. That’s not nice.
Thats fine, but not a lot of “the masses” are going to need to edit multiple audio tracks, and I think you sould just use garageband for this (I know separate program, but it can be done easily). I don’t think you can fault Apple for “breaking” plugins. Anytime a new app is released I just assume that my plugins will be broken, so I generally will either wait until there is an update to said plugin, or I deal without, or use the new and old versions in concert. I don’t blame Apple for this though as it is not their responsibility to ensure that all 3rd party stuff continues to work with their app, it is the resposibility of the 3rd party to update their app or plugin IMHO.
