It lists the relevant files on most discs I've searched for and gives a duration for each file, which might save you some time.

Also, I haven't use this but I've heard people speak of a program called FileBot, which is apparently handy for renaming bulk amounts of media files, but I'm not sure how it works (I think it needs the IMDb ID or something like that)?

I often look for a review of a disc on blu-ray.com since they usually list (and name) all the special features on a disc, often with time stamps.
