I used my Macbook Pro to burn photos(jpeg format) to a DVD-R disc, and my Sony DVD player says it's compatible with jpeg and DVD-R format but for some reason it doesn't recognize the DVD. The disc works on my Windows machine; it sees the photos, no problem, proving the disc is probably fine. I used Finder to burn the disc. It's just a bunch of jpegs, not a slideshow. The Sony player has played similar jpeg DVDs that I burned with a Windows PC. What's going on? Can anyone help?
