OK, found two additional problems:
- On unknown codecs, the current code simply dumped core because of
  closing a codec context, that was never opened.
  (Fix is in CVS now...)

- More interestingly:
  If you don't specify it at compile time of ffmpeg, it will be build

  with AC3-encoding support

  This is a licensing issue GPL <-> LGPL, since the used AC3-decoder is
  GPL and you change the license of ffmpeg to GPL, if you enable it
  at compile time.

  Not a big problem for us, but could the windows-folks please look into
  the windows build of ffmpeg bundled with Blender and make sure
  AC3-decoding is enabled?

  It is rather silly, to generate a MPEG-2 file, that can't be opened
  later by the same program ;-)
