What're the chances of an iso's video size being reduced during dvd ripping...?

    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.

    A wide screen SD video would be 720 x 404 and then letterboxed.

    An iso is an image of the disc so no manipulation of the content on the disc should have occurred. The software you used just removed the letterbox from the video so instead of a 720x480 image with black bars on the top and bottom you have a 720x404 image of just the concert itself.

    Thank you for the replies. That's really the only thing I wasn't sure about. Now I know. ;)
