I just thought I'd include this link for anyone willing to interpret it.
Apple iDVD pageFrom the page: "Save your original photos
Want to add your original photos to your DVD? With a single click, tell iDVD to include your original, hi-resolution digital photos with your DVD when you create a slideshow. You can play this DVD in most regular DVD players, but now when you place the same DVD in your Macintosh, or any other DVD-capable computer, you’ll have access to all the full-quality photos for printing, emailing to friends and family, or adding to your iPhoto library.
In addition to adding photo originals to your discs, iDVD lets you include many other kinds of data files, including AppleWorks, Word, PowerPoint and Excel files, as well as URL links to a DVD-ROM folder that can be accessed by any computer — Mac or PC. So that in addition to watching your DVD on their TV, your family and friends can also put your DVD disc in their computer and access the original photos or extra files you’ve included."
