So far I see the following two points (the first one is the most...serious):

• Starting from the TVDB ID, there will be one query to obtain the TheMovieDB_ID, another one to obtain the IMDB ID and a third one to query the IMDb site for updating the rates...it is also true that this will happen just at the first update (i.e. the IMDB ID should be saved for the next runs)

or you can cache this pairs TVDB ID->IMDB ID in local table -> write to file after, read from file before.

All the users will have to create their own API key...I don't want to provide support for that too!

You will make one API key only for application and this way is ok (for testing my little prog I used key from other app also)
