If there is one TV set with the issue, that's a problem.

It's the same problem with ME+D in A/52 audio.  If there's one TV set 
that can't hear both dialogue and music-&-effects, broadcasters can't 
utilize ME+D instead of CM to same bandwidth on multilingual shows.

So, until everyone knows that every TV set with the problem has been 
destroyed, it's still a problem.

TTFN,
Mark
