What does this icon represent (on back of Finding Nemo BD)?

Not 100% certain, but I believe that it denotes the availability of "Descriptive Audio" for the blind and visually impaired. Someone please correct me if I am wrong.

Almost correct.

It's called "Descriptive Video", not "Descriptive Audio". In other words, it describes what you're supposed to be seeing in the video.

It's like having a person watching the movie with you, telling you everything that is happening visually.

That's correct. The full term is Descriptive Video Service (DVS) and it should show up as an option when you first pop-in the Finding Nemo disc.

However, I think this is grammatically incorrect and would prefer the term "descriptive audio". Descriptive is an adjective - it is the audio that is being descriptive and the video that is being described, thus it should be "descriptive audio service" or "video description service". Oh well...

Is there a list somewhere on this site or somewhere on the web that lists *all* blu-rays released so far that include a Descriptive Video Service (DVS) track?

It's far from complete, but here is the list that I have:

Same list filtered to just US releases:

Thanks for the link. Nice site, btw.

It's funny, several Blu-rays that I have that include a DVS track I like listening to as almost background chatter when I have trouble sleeping late at night or when I'm working or reading. It's like someone reading the script to me like an audio book.

I'd heard about DVS before, but reading this thread made me really contemplate it. I assume that if I were blind I'd get much more entertainment out of an audio book than a movie with a DVS track. But I suppose DVS would be really useful in allowing the blind to "watch" a movie together with others who can see.

What would be cool is, since the current players are all network connected at this point and now often have things like Bluetooth connectivity, if they could use that tech to be able to send that audio channel to a set of WiFi or Bluetooth headphones so someone could hear it without everyone hearing it.
