hey syskin,

you question describes exactly what happens when DX50IVOP is enabled.
the encoder logic is:

   if (xvid_detects_a_scenechange)
   {
      if (number_of_queued_bframes > 0)
      {
         pop the last bframe & encode it as a P-frame
      }
      encode any remaining queued bframes as B-frames
   }

also, where everyone gone? ircnet#xvid has been empty these past days.
