Are these photos and videos you uploaded?
No I didn't see that. You can save videos using this:
Photos you can just right click on and go to Download Linked File As. Is this DVD copy protected?
Yes you drag the disk to the Handbrake window to convert it there are many options I can help by remote if you wish
Of course that is up to you but you can also use Apple Keynote which I believe is superior to PowerPoint. When you drag the DVD to Handbrake you choose which chapters or titles you want to convert
Sorry I'll send it again
Can you click on it now?
