Soon after I got my HR10-250, the CC Appeared. IInitially I could not figure out how to turn it on or off. I made a call to DirecTV technical support. The "technician" insisted that CC was always controlled by the TV set and that the HR10-250 had nothing to do with it. I knew this was BS and asked that my call be escalated, but she refused.

It is not simple to turn CC on or off. I found I had to navigate to the speaker or Dolby Digital icon on the "Channel Banner" that appears when you press the "info" button. If the icon is bright, you can highlight it and press the select button to choose an alternate audio track.

I don't see any good way to automate the process by using a macro, because the selections available differ as a function of the program content. I think you have no choice but to go through the menu process one step at a time.
