You guys had it easy.
Mobile devices being what they are, listening in the car to the radio broadcast then switching over to watching as i got out and left the bluetooth connection, when i got back in and watched a bit, the reestablished bluetooth picked up the radio broadcast where i left off and overlayed it on the tv broadcast audio, so i got a couple of extra announcers out of sync by maybe 15 minutes... Eventually i restarted the app...
