What you want can't be done, even on the newest 6.0.
You'll have to move the markers one at a time.
Wow, that seems surprisingly illogical by design... so if you ever need to go back and edit a bit at the beginning of the project after you have created markers/DVD menue, you are out of luck? What is the a reason for this?
If those were Clip Markers, and attached to the Clip, they would move.
They are not. They are attached to the Timeline, so as the Clips move, those Encore Markers stay where you placed them - attached to the Timeline.
Thanks everyone. So Encore markers are what are used for DVD menue markers? Can clip markers be used instead? If so, how wouls I go about that?
No on the Clip Markers = Encore Chapter Markers. However, one could use Clip Markers, until the edit is almost ready to Dynamically Link to En, and then they could be replaced with En Markers, though only by hand, to the best of my knowledge.
Maybe time for a Feature Request for something like "Select all Markers, and convert to ____ Markers?"
OK it looks like that is the solution to my issue then... I have instead created unnamed markers right where the DVD menu markers are so that when I then slide the whole project... all I have to do is "snap" each DVD menu marker to it's corresponding unnamed marker. A bit time consuming, but worth not having to find and readjust for perfect placement each time I do an edit.
