@MSlion, in the Uk at least the dvds of game of thrones actually come with the audio description anyway, you can also get it if the series is being shown on tv and you've got your tv options set correctly.
I'm not sure about online streaming services I'm afraid, someone did say audio description wasn't available on netflicks but I don't have net flicks myself I can't confirm.
@Orko, I personally love having both the audio description and video together. The video allows me to get what I can with the small amount of vision I do have, but the audio description insures that I don't miss details o get lost. If the audio description is there I can see the objects being described and know what they are without having to use logic and guesswork, indeed Ironically I am often able to appreciate the video more if I have the audio description along side.
Even for totally blind people, if your watching with someone else often they want the audio description too, so they know what your getting, indeed I have a couple of fully sighted friends who always use the audio description after seeing audio described films with me, I even have one friend who always uses audio description now on his own because he says it lets him follow what's going on more easily .
I do these days do none visual stuff with just! the description with my lady, but my preference would always be to have both where possible.
With our dreaming and singing, Ceaseless and sorrowless we! The glory about us clinging Of the glorious futures we see,
Our souls with high music ringing; O men! It must ever be
That we dwell in our dreaming and singing, A little apart from ye. (Arthur O'Shaughnessy 1873.)
