FreeEnc

FreeEnc is a mpeg-2 encoder that uses the avcodec library. From the website:

  • Allows the use of templates
  • Takes avisynth scripts as input
  • Highly tweakable: all avcodec parameters are available for tweaking
  • Highly tweaked: comes with templates already configured for great results
  • Lots of stats: average bitrate, time to end and much more
  • Shows a Bitrate Viewer-like bitrate allocation graph in real time

If this helps you encode those DVDs, then by all means also try DIKO from the same author.
