Why does my Apple Close Caption not working???

[AnimalPaintball]

I have set it to regular and even enhanced, but every time I watch any rented movie or tv show nothing shows.

Id really like to have it, since I can watch movies with the volume very low (while I can still read what is going on), I have a newborn, and trying to keep things quite so he can sleep

Any info would be much appreciated

Only some content on the iTunes Store has Closed Captions, you can identify it by the small CC icon next to it and you can search for it using the Power Search.

AFAIK there are no TV Shows with Closed Caption available.
