Does Movie Studio 9 have an upper limit on the size of the video file that can be shrunk to fit a single DVD? I'm using Vegas Movie Studio 9 (Build 55) on a 64-bit Windows 7 computer. The video consists of three mpg files and a jpg in front and at the end totaling 3-hours, 46-minutes in length. The file renders to a 10-GB mpa file and/or a 10.5-GB mpg file. When I attempt to burn a DVD using DVD Architect Studio 4.5d (Build 107) optimizing with "Fit-to-disc", I get a message that says "Media file is too big and could not fit into single DVD disc". I could not find anywhere in the literature where it says what "too big" is. Any suggestions? Note: Roxio Creator 2010 does the same thing which is why I moved to Vegas Movie Studio... so I'm new.
