There is a similar 'importMetadata()' method for Recorded objects, 
matching one recording entry in the `recorded` table.  However, the 
Video Library was designed for arbitrary addition of content, the 
Recording Library was not.  There are around a dozen tables you need to 
touch to add a single fake recording to MythTV, and a few additional 
that carry optional data.  For some not-so-light reading, dig through 
MiroBridge for what is needed to add your own files as recordings.
