Not exactly. MythTV uses independent metadata grabbers for television 
and movies, and uses TheTVDB.com and TheMovieDb.org, respectively, for 
those purposes. Typically, anything with either a subtitle, or season 
and episode number, is treated as a television episode, attempting to 
use the TV grabber, before falling through to the movie grabber. Other 
content just tries to use the movie grabber directly.

What you are seeing is a successful television show lookup, resulting in 
the reference number 81386...

... but something goes wrong, causing it to pull the data for that 
reference number using the movie grabber. It's part 5 by the way.

By default, all this is off. The batch metadata grabber must be run 
manually, or configured to automatically run after a manually triggered 
scan.
