Why can't is use iDVD to burn on a DVD-RW disk?
I 2012 I used iDVD to burn several slideshows and movies onto DVD-RW disks, and they all play just fine on my Sony DVD player. I now have a new project in iDVD but when I burned the movie it went through all of the steps and verified the disk; however, when I tried to open it on my Mac, it openedwith Libre Office. What on earth is going on? Must I use a DVD-R disk? I have several blank DVD-RW disks and would like to use them up. Thanks for any help you can provide.
