OK - what I'm seeing looks like a problem with the new A/V sync code.

When a PiP is added, A/V sync (for the main player) breaks and it
can't recover. This line repeats and repeats:-

2020-03-06 09:54:57.943347 I [17324/17324] CoreContext
mythplayer.cpp:1793:AVSync  Player(0): Dropping frame: Video is behind
by 65ms

with the same 65ms.

A quick pause and unpause and everything is fine again.

Yes - confirmed - though I think that may have been a problem for a while.

For what its worth, at some point I'm going to remove PiP support and
re-build it. The code is a horror show.
