How to install Nero Digital Video Encoder?

I have a full version of Nero 6 Ultra Edition with all updates, so it should include all of Nero Digital. But I was running into problems with Nero Showtime, so I ran Sherlock 2.0 (from to find out whether any of my codecs are bad. Well, Sherlock says, for Nero Digital Video Encoder:

“The driver file for this codec was not found.”

Am I supposed to have this codec installed somewhere? If yes, why didn’t Nero install it properly? If not, why is it mentioned in Sherlock’s list at all (as if the codec was mentioned in the registry somewhere but not actually installed)?
