It looks like the episode/movie recognition is pretty good. I'm not really sure of the implementation details, which impresses me.
Boxee recognized about 3/4ths of my TV shows and all of my movies.
However, when I go to go to Recognize a TV show, for example
I select "TV show", it brings me to
"Enter series title, season and episode numbers separated by comma..."
I enter The Office, Season 5, Episode 1. I press ok.
It brings up a list:
The Office (US)
The Office (UK)
The Office (1995)
The Principal's Office
The 1970s Office
I select The Office (US).
I see a momentary "Resolving...", followed by no change in the screen. It's like it doesn't accept my resolving, or it doesn't proceed for some reason.
The same occurs when I put "The Office, 5, 1" and "The Office" into the text box.
