I want to copy a DVD slideshow I created to a DVD (no problem) but I also want to copy the slideshow data files to the same DVD. I want the DVD to play on a regular DVD player, but also want to access the data files on my computer.

I know this is possible because commercial DVDs have both movies and DVD-rom data files. Is this possible for amateurs without spending a lot of money? Right now I have DVD Shrink and OEM Nero that came with my computer several years ago.

Thanks.
