Regarding hashing.. can a better mechanism be made to find subtitles? The reason I'm asking is because in my experience I get no matches (since I have my own DVD rips). Even with other movies, hashes are not available for many videos.
So.. what if in addition to hashing, movies were matched by duration (millisecs or secs)? In that case most DVD rips would be matched, regardless of the encoding. Same with blu-ray.. right? Would that be possible?
