I am using DVD Arch 4.0a and when I drag my wedding video (file size 2.5g) over to the work area and drop it, the bottom corner is saying that the disc space used is 5.0g. Which of course is too big. I have never had one file that was too big. The video on the vegas timeline is about 120mins. Anyone know what to do? Or why this file size is doubling in DVDA?
