I bought a blu-ray movie that includes the blu-ray disc, DVD disc, and a Digital Copy disc. I used the digital copy to download the movie in iTunes on OS X, which works fine. However, the movie in iTunes, like many others, does not have subtitles or closed captions. I'm hearing impaired and I rely on these to be able to understand the movie.
From what I've read, the iTunes movie has DRM protection on it. I can find the needed subtitles (SRT file) for the movie, but I wouldn't know where to begin to try to encode it into the movie without messing up the DRM. I want to stay as legal as possible. Is there a way I can do this?
