I did not find out the hard way, as iTunes gave a warning...which I heeded, and did not sync. The videos and photos are the same ones that are on the Web site. You could readily download the photos from there, but the videos are imbedded with Flash, so I have not figured a way to copy or download them. I suspect they may also be available on YouTube, but that's hard to rob, too. They might also exist on the DVD, too. I have not had time to view it as yet.
Biggest problem I have is that after my download, the computer crashed while the iPod was attached, so iTunes no longer recognizes the iPod. If I reset it, I will lose everything. I backed up the iPod before I did anything, but the movies must have been protected, since they did not copy to the backup folder. None of this is really that big a deal, it is the same standard videos, and nothing really special.
