Q: “I have created an album in iPhoto from a selection of 1,000 photos I took on vacation. I want to export these to play from a thumb drive on a TV. When I export a Slideshow, it created an .m4v file. Due to DRM restrictions I discovered I don't have permission to play my own .m4v! I can't even play it on the laptop that produced the .m4v. How can I export iPhoto slideshow to MP4? Surely, I can't be the first person to experience this conundrum. What is the solution?”
