This is a strange behavior I am suddenly (lately) encountering in Encore: While thorough testing during creation of (a partially 4K) timeline bluray project, everything works just fine -- flawlessly. However, the burned bluray (created from a .iso image file of size 16+GB), on clicking the first or the second buttons, starts playing the item on the third button. The items on the first two buttons are not playable.
Here is a description of the specific menu: The first two buttons point to two timelines respectively. The third button is linked to (i.e. points to) a slideshow. There are 4 more other buttons that point to more timelines and slideshows.
It should be noted that this is a multi-menu project, consisting of more timelines and slideshows. There are several other similar errors in some of the other menus.
I have made tens of blurays over the last several months, some projects being large and quite complex, without any problems. The only thing new in the current project is that it has some 4K timelines, and some slideshows that contain stills extracted from the 4K timelines via Premiere Pro.
Any comments will be appreciated.
