Not to pick nits, but I really don't want to compute the MD5SUM of a 4GB DVD before I can play it. Maybe hash the header or the metadata (if there is any) instead?

May be md5 the first hundred and last hundred mb's? Add 10 samples from the middle of the movie taken at equal distances calculated based on the size of the file.

Having said that I don't mind having to compute 4gb md5's, since that also helps me to check the integrity of the file at a later date.

opensubtitles hashes only the initial and final 64kB.
