I was testing out the original version of this patch, and I came across
a segfault.  In the FindPosition method of AvFormatDecoder, you had a
couple of while loops like:

  while (m_positionMap[lower].pos > desired_value && lower >= 0)

and 

  while (m_positionMap[upper].pos > desired_value &&
         upper < (int)m_positionMap.size())

On my system, there were a few occasions where it tried to access
m_positionMap with a bad index before it did the bounds check, and
choked :(

P.S. Glad to hear the AC3 stuff works well on your system.  Out of
curiosity, what kind of soundcard are you using?  The nForce2 stuff on
my motherboard isn't working as well as I'd like it to, and I haven't
come up with a simple fix for it yet besides maybe using different
hardware...
