Automatic recognition of DVD/BD directory tries
I'd think, it would be more useful for the server to recognize the VIDEO_TS directory as special and create the equivalent of pressing "Play Movie" on the DVD's menu on the fly automatically. If the DVD contains multiple audio options, it would be nice to see the same movie listed multiple times -- so that the desired audio-track can be picked using the TV's remote.
BlueRay's may be more complicated, but DVDs are fairly well-known, aren't they?
