I have 4 mov files that I burned on a DVD. Once burn, the DVD starts the DVD reader (on my Mac) but the screen stays black. I have a Mac Pro with 10.7.5. When I put the DVD on a PC and tell it to open in Windows Media Player, it opens, but the main menu in not working. When I click on one of the 4 titles, it just alternate between full screen and the menu view. I have access to the files in the right column and they play when I click on them. In the menu in the right column, the DVD is named unknown DVD. I have Toast 11.1
Thanks for your help.
