Closed Captioning not brought to you by Apple
Russell Beattie brings up a very good point in a recent post over at his blog: "...I couldn't share [the shows] with my wife. She has some problems with her hearing, and isn't a native English speaker. So in our house, the subtitles are always on the TV so she doesn't miss anything....The fact that iTunes Video comes without subtitles is disappointing.... Dear Apple: Please fix this. It's a real problem for those people who want to enjoy your service, but need subtitles."
I don't know if it would be possible, currently, for the shows to have a closed captioning on and off toggle in iTunes or the new video capable iPod, but it wouldn't be too difficult for the iTMS to offer both captioned and non-captioned versions of all the television shows listed in the iTMS. I hope this is a service that they add in the near future, both for the hearing impaired and for those of us riding the subway who like to be able to listen for our stop and still follow what's going on in the show.
