We are working on a movie for our school's 200th anniversary, and we were planning to do an audio commentary. Is there any way we could program this to our DVD using any software that's consumer oriented (currently we are using Adobe Premiere 2, we can also use FC if necesary) We use both Windows and Mac, so any solution will do. Our only other option is to use the same footage twice, but this isn't the best solution. Is there any way we can use the same image but different sound?
