ffmpegX_0.0.4aでVOBを「MPEG2」で書き出そうとしたら、

Mpeg encoder engine not found:
please install mpeg2enc binary file first

To comply with MPEG licensing terms, the actual encoder
component has not been packaged with ffmpegX GUI.

Compile mpeg2enc from the sources available at mjpeg.
sourceforge.net or fink.sourceforge.net (package 'mjpegtools')
and then copy the binary into /usr/bin/ with the following terminal commands:

sudo cp /path/to/mpeg2enc /usr/bin/mpeg2enc
(where /path/to/ is the full path to the binary file in your disk)
sudo chmod 755 /usr/bin/mpeg2enc rehash

You should also check MPEG licensing terms available at
http://www.mpegla.com/ and comply with them.

と出てきて出来ないようなのですが、「mpeg2enc」って入手しないと
いけないのかな？

ちなみに、QTの「QTMPEGExport.component」は入ってます。
