i just tried transcode based on an example invocation here:

http://users.dslextreme.com/~craig.lawson/linux_notes/video.html

and ran into a problem that seems to be making the rounds:

...
[export_ffmpeg.so] could not open FFMPEG codec
[transcode] warning : (encoder.c) video export module error: init failed
[transcode] critical: failed to init encoder
...

  so now i'll give mencoder a shot and see if i run into the same
problem.  thanks.  (BTW, yes, i do have the ffmpeg package installed.)
