Andrew, IMDB does not have this info, and unfortunately DVD fingerprints of the type that the EMI emits are very specific to itself and its endpoint.
This is a much tougher nut to crack than would first appear, especially since almost nobody has this information. If you'd like, I can explain the problem in more detail...
I understand the DVD fingerprint problem. What I am interested in is the much richer data available from IMDB about each movie. It may be that a hybrid solution is possible where we allow the DVD to be ID'd using the EMI then we use that data to query the IMDB. This would be deliver a massive improvement in the attribute data per DVD.
As far as i can see this is technically feasible. What your view?
All the best
