Just upgraded from old WDTV Live Plus to latest WDTV Live

Ok, I’ve playing around with the various file naming conventions and have not had any luck.  It seems like for the TV shows (as well as the music) it is still trying to use the TMDB meta source manager instead of TVDB, which brings me back to my question of how does it know which source manager to use, esp since I have not seen a way to assign a particular meta source manager to a particular network share directory.  The reason why I think it is always using the TMDB manager is because if I rename my Sienfeld - S01E01 to just Sienfeld, it will find two movies related to Jerry Sienfeld, but not any TV show listings, so I still don’t understand how it knows if a given rip is a movie, TV or music.

On a related note, is there a way to use another meta-source manager, i.e. IMDB.  I know there is a choice to Add New Meta-Source, but when I select it, it says no storage present, like it is looking for a local meta-data source.  Can I just add a URL for IMDB somehow?

Thanks
