I have this problem too. I think he means he tried running the individual
commands because the automatic way wasn't working. Here is the output I got.

Encode started:  Thu Nov  4 01:38:44 2004
Waiting for mythtranscode to set up the fifos.
Waiting for mythtranscode to set up the fifos.
Starting transcode.
processed:  0 of 0 frames (0.00%), 0 fps

And it would stay there forever.
When I run it with debug these are the commands it prints.

Like the original poster said, apparently the fifo directories are not being
automatically created.

You need to create the fifodir by hand when you run things by hand. 
nuvexport normally does this for you.
