DVD created by Toast-DVD not readable
As a test case, I dragged a .mov clip and a .MPG clip into the Toast DVD 2.4.3 Content Area, with Video button pushed and DVD-Video drop down chosen. On the right, Options is chosen, Format is DVD-Video, and Menu Style is no menus. Quality is Good, and I selected Auto-play, and Play continuously. Destination Disk Image. Hit the red Save button. It makes the disk image document. Click that and get the disk image. When I burn a DVD-R disc from either (using the Finder pop up menu), it plays on my Mac, but not on my Sony Blu-ray player, which is good at reading discs normally. Any thoughts?
All of this is in the North America region, using NTSC. MacOS is ver 10.15.7.
