Gee thanks. It's not like I haven't already researched the issue. If you read that post, it's a bunch of nonsense gobbleygook and FUD that works out to, we don't want to do it.
He says they would have to reencode the entire library with subtitles enabled in order to stream the captions. This is of course BS because the captions are not video data and do not need to be encoded.
He says that they are developing special display technology that would display the text as a separate stream in silverlight. Again FUD, I have written programs that display text in silverlight. It's quite easy, as you would expect.
The data for all of the captions for a movie is usually around 100 KB and is freely available for use on nearly every dvd.
The bottom line is that they do not care to have their programmers waste even 10 minutes on the Deaf community
