After re-reading the original post, I want to say it seems more recent than last January. More like just in the last 2 or 3 months I realized I have to keep jumpstarting the show again. (And if it _is_ a media glitch, it's arrival is not necessarily aligned with a software upgrade.)
It seems like the screen is locked waiting for something to complete (SKIP, OK, etc.,) or maybe a timer that didn't get started. Since there is no way to kick it, you have to exit and resume.
