Honestly, I wouldn’t mind a little pop-up before the movie on Blu-Rays asking which track it should play and explaining that those listening on TVs should choose the basic stereo.
There’s actually precedent for that. When DTS first hit the home media scene, not all DVD players supported it, so there would be a screen with a description of DTS and the option to enable it or choose Dolby Digital before taking you to the main menu.
Actually, now that I think about it, my Hell Freezes Over concert DVD has that.
