Maybe I'm just late to the party, but in case not, wanted to let folks know that using the Second Screen app to hop between discs in a multi-volume set dramatically speeds-up the transition. Even if you aren't waiting for the projector to swap back-and-forth from content-to-menu-to-content, the lack of any changing by the player also cuts the time down a lot (I'm finding it cuts the time roughly in half,) so it would probably work just as well for any other content (as long as you aren't changing between resolutions/features.)
It would be nice if we could directly swap discs using a selection in the Navigation section of the pop-up menu, and it's a little inconvenient if you normally use something else, but a workaround for those who are interested.
