I'm in the final stages of creating my first DVD using this software. When I went to make the movie, it said that the file size was 4800MB, which won't fit on the DVD. So I took half of it out and made another file (figuring I would just have 2 DVDs) to make the file size smaller, but it keeps telling me that it's still 4800MBs and that it won't fit!!! Does anyone know what I'm doing wrong? Did I skip a step somewhere??? Help please!
