* 6b402ca5a3 2019/02/15 Peter Bennett : AVSync2: Improve resync speed and accuracy

* 90b4ec347f 2019/02/15 Peter Bennett : AVSync2: Fix never-ending stutter on Live TV


The change in 6a5fb07fa1 was to address the issue of frame count and 
elapsed time getting out of sync and it worked surprisingly well, but 
there are side-effects..

In my opinion playback should use timestamps rather than frame count to 
determine elapsed time, but that would be a major change.

I believe that David Engel , Mark Spieth and John Pilkington had 
problems with elapsed time going at the wrong rate before I made the fix.

The problem was worst with the built in deinterlace of the shield and in 
particular if you were running at increased speed (e.g. 1.5x).
