Comment (by Dan203):
I had reports from 3 customers, one using a Popcorn Hour, one using a
"Panasonic TV" and another using Media Player Classic. All of them
complained that either the file did not play at all or it playing
squished. I put out a build where the only change I made was commenting
out that one line that sets the DisplayUnit and all 3 reported it fixed
the problem.
Perhaps I'm wrong in my assessment of the spec, but all I know is that
when the value set to 3 it fails on at least 3 players and with it set to
0 or not set at all it works in every player I've tried. And when I remux
the file with MKVMerge that value is removed, so at the very least it
seems to be unnecessary.
