  If it was interlaced content then I believe it.  Doing something is
better than nothing. :)

  Jerky might just be dropping frames too!  Also, you should make sure
that you're either running as root or have sufficient access to /dev/rtc
to get high resolution timing.  Otherwise the high framerate isn't
possible.

  I'm trying to now improve the autodetection and documentation of
performance problems.

  Run 'tvtime -s' to see an indication whenever an input frame has been
missed.  Also, please hit 'd' while tvtime is running using something
simple like linear interpolation and email me the stats you get (they're
printed to stderr).  I'm curious.

  Many thanks,
  Billy
