Comment(by markspieth):

 patch 4 has the previous improvements plus:

 1. better unpause and start playing response. This almost eliminates the
 frame doubling required at start of play or after seek/unpause. Reduces
 the zero write latency when audio is paused, and  discards any audio
 packets which come before the first video packet.

 2. faster avsync convergence. convergence is now adjusted by a frame
 interval period.

 item 1 can be split from the patch if desired. audiooutputbase.cpp and

 the vsync patch can also be split as it is also independent on the other
 changes in NVP.
