Is there a way to remove files from a disc image that has already been written? Perhaps a disc image "editor"? I have a video DVD that I made a while back that is too large for one DVD so it's formatted for a Double Layer DVD. Since burning that image, I have deleted all of the reference files. I now need to burn most of the contents to a single-layer DVD... but I don't need everything that's on the image. I would love to take out a few of the video files from the image, thus shrinking the image and preserving the DVD menus contained in the DVD. Any ideas? THANK YOU!
