Thank you for getting back to me! I hope I don't frustrate you because I am not sure about a couple of items you ask about. I am not much of a computer whiz. Anyway, this is what I DO know:
1.) I am using Mac OS X, version 10.4.11
2.) I am using imovie 08.
3.) I don't know what the audio files are. The audio I have comes from the videos and I am also downloading music to insert from itunes.
4.) I don't know what an "external audio interface" is.
5.) I checked for updates on imovie and it looks like there are some I can install. I am worried about doing this since I have been working on this project for many hours. Is there any chance when I install updates that it could mess up the project I have going?
Thanks for your time and help. I am sorry my knowledge is lacking!!
