I have a similar problem too. I want the menu button to go to my scenes menu when it is pressed in the film, remembering if subs are on or off. It isn’t possible in Encore as it is.
I have been advised that maybe setting a popup being associated with a timeline is the way to go but if I do this, I will have to have several timelines of the same video which will bump the size of the BD considerably.
I too have looked at Blustreak Tracer but have had no response from the makers AT ALL!
This does not fill me with confidence if I were to lay down the necessary $600 to buy all of their software.
Are they even still in business? Not helpful at all.
