Again, may have been covered before, but thinking about other Feature Request like this - http://forum.icetv.com.au/iceforum/index.php?topic=3091.msg15178#msg15178 (http://forum.icetv.com.au/iceforum/index.php?topic=3091.msg15178#msg15178) - it would be cool to move what really is the 'type' (Movie, Documentary, Mini Series, Short Film...) out of the Genre tag...and leave Genre for things like Comedy, Western, Historical.
So create a new metadata value of Type or whatever you want to call it.
