If your computer has no TV tuner, an optional analog or digital TV tuner is required to play and record TV in Windows Media Center.
If you want spoken audio to be in text format when you are watching TV shows and DVDs, you can turn on closed captioning in Windows Media Center.
By default, closed captioning is turned on for Windows Media Center and Windows Media Center Extender when both are set to Mute. You can change this setting if you want.
Windows Media Center displays closed captioning that is broadcast by your TV service provider. Check with your service provider to see if they broadcast closed captioning for the TV show you want to watch.
On the start screen, scroll to Tasks, click settings, click TV or DVD, and then click Closed Captioning. In some regions, you may need to select Subtitles instead of Closed Captioning.
Under Caption Display, click either On, Off, or On when muted.
After you have completed your changes, click Save to return to the settings screen.
If you have an analog TV signal and you want to turn on closed captioning, you need to specify closed captioning for analog channels for closed captioning to work correctly.
On the start screen, scroll to Tasks, click settings, click TV, and then click Closed Captioning.
Under Basic Captioning, click CC1.
When you have completed your changes, click Save to return to the settings screen.
Digital TV channels provide further closed captions options in addition to Basic Captioning. Windows Media Center will attempt to select closed captions in the language specified in the Preferred Language setting. Note that certain broadcasts may not specify the language that is associated with each captioning service.
Under Preferred Language, select a language.
