Actually, the encode looks good but I'm surprised because mencoder/xvid
has encoded with the requested bitrate before for dvd rips. The source
is not blurry.

I've tried testing 60sec clips...  for one test
MEncoder dev-CVS-040117-00:00-3.3.3 results in 720.6 kbps
MEncoder dev-CVS-040215-00:00-3.3.3 gives 662.7 kbps

I'm using xvidcore-1.0.0-rc2 .
