Improve tracking of 'playing time' metrics

Some field records sometimes showed non-zero frames played, but zero
playback time; a combination that should not be possible. Tracked to
alternate exit conditions that didn't go through the existing 'update
the stat here'.  Now managing time at some other identified possible
paths for playback exit.
