I just reproduced this problem. transcode fails if more than one 
parameter is passed to the module. Modules without any parameters or 
just one parameter work.

I just posted a correspondent report to the transcode developers.

Why? dvd::rip removes the socket just after transcode was started (which
creates the socket). This way the socket doesn't leak if something fail
badly, e.g. a dvd::rip or transcode crash. The filesystem entry is not 
needed for proper operation once both processes are connected to the 
socket, which was represented by it.

Yep, transcode creates the socket.

Hmm, what did you expect? ;)
