I've been capturing video as mpeg and burning DVD CDs using Pinnacle Studio 8. Burning with Best Quality the DVD is supposed to hold about an hour video. I Edit and "Make Movie" with the biggest mpeg the program says the DVD will hold. It usually says I have just seconds free left on the DVD. My question is, the finished DVDs are not burned nearly to the outer edge. There's about 1/4 to 3/8 inch unburned. It looks like it could hold another 10 minutes or so of video. Is this normal for DVDs?
