It doesn't work for me, I'm using:

  #define NEW_DURATION_WEIGHT 0.05

  #define MAX_PLAYOUT_BUFFER_DURATION 0.25 // (seconds)

Because we were seeing (sometimes) some packets being sent out too
late.  I think this was because not every packet has a PCR value
on it, so the fTSPacketDurationEstimate was going wrong quickly.
Part of the solution was to increase the MAX_PLAY_BUF_DUR so that
the STB had a larger buffer to work around the resulting jitter.

As we patch the library anyway (yes I'm aware of the "don't do
it" rule) it wouldn't really affect us, but I thought I'd mention
that 0.1 doesn't work for everyone.
