I can's explain this...

And I wasn't sure of where to post it. I'm looking for a little help.

I can't figure out what the hell is going on. I have a certain DVD with files on it. It's a 4.7GB data DVD. I can create an ISO image of the DVD on my hard drive and it comes to 4.36GB. I can mount it in a virtual drive and burn it to another DVD, both work flawlessly. However, when I extract the files from the ISO file or copy them from a burned DVD, the files come to over 13GB on my hard drive. How is this possible? Windows shows the DVD as being 4.36GB, but when I highlight the files and go to their properties, it says there are over 13GB!

This makes it very hard to edit the DVD, which is what I'd like to do. WTH is going on here? Is there something just freaking out, or is there a program I can use to copy the raw files to the HD without the extra baggage (that shouldn't.... physically be able to be there...) I'm at a loss. Thanks for any help, and if this needs to be moved, by all means.
