I have just started going through my DVDPedia library to clean up the data I have and one feature I would dearly LOVE to have is the ability to clean up the data by removing duplicates. I don't mean duplicate DVDs, but rather duplicate entries in the Director, Producer, and Starring fields. Some data from various sources can contain duplicate entries in these fields, especially for TV series and box sets. If there was some way of automatically removing these duplicate entries it would be a god-send!
As an example: I have the Babylon 5 DVDs, and some of them list all the actors for each episode in the Starring field. Now obviously many actors appear in most (if not all) episodes, so their names are listed up to 20 times! Manually tidying these up is a very slow, and not particularly enjoyable, prospect. 8^/
