I'm starting to gain an appreciation for how tough this BR menu authoring can be.......MultiAVCHD seems to shut off full-menu capability when it enters BR Mode. Adobe Encore seems to have disappeared from the planet, since Adobe no longer supports it. Finding older versions is no small task.

Using the Pop-Up menu feature in MultiAVCHD seems risky, since there is no preview feature there.

There don't seem to be a lot of other options unless one is willing to break the bank.

Seems like I'm going to burn the basic BR structure with all the audio options and some subtitles and wait for the pros to handle the menus. At least the GOUT chapter markers will port over and it will be much smoother skipping around the film. I'm sure time search will work as well.
