Ok. Here's the situation. I was given a DVD iso to convert into a m4v file. I'm wondering if there's the off chance that when the person who ripped the DVD into an iso file the actual video size (height and width) was reduced or if it's the full size. I'm unfamiliar with iso files and how they work. Is that even a possibility? The DVD they ripped contained one video with a run time just under 30 minutes. The iso file size was 2.06 gb. There isn't anything else on the disc. The video size when I converted it turned out to be 720 x 404 (actual). I want to make sure they ripped the iso correctly and that they're getting close to the same video size as when they watch the DVD on their tv. Thanks to anybody who can answer my question.
