I tried something like this just now. It works, but, may not for a particular situation. For instance, with a split image set, you'd have to mount the image to a virtual drive first. If it's not split, then, use LUK's suggestion. Then, note the start time listed. Then, open a DVD player and load the contents of the disc in whatever way into the play and go to that time location and see if the contents match.
For split images, there's an extra step. But, you won't be able to do that yet until the next version comes out.
