The team at SageTV continues their constant stream of new beta releases for version 6.5. A little over a week ago they released 6.5.13 which added closed captioning to its list of treasured features along with several additional new features and bug fixes. CC support has been one of the more requested features along with the subtitle support (added in 6.5.12).
I successfully tried this out with my Hauppauge PVR500 tuner and Silcon Dust HDHR tuners. While I probably won’t use captioning all that much, it will be very nice for those that are hearing impaired and for those who need to turn down the sound at certain times. I’ll use it to show sports when I have company over but want to play music while the game is on.
