@phonemancan Check that described video is turned off by completing the following steps:
Press the Menu button then select Settings
Scroll down and select Audio
Scroll right to DVS
Press Down then the Left or Right arrow to toggle on or off
Alternatively, you can use the "D" button on the remote to turn this feature on/off. When watching a channel with DVS this feature can also be toggled on or off through the DVS/Language option, however, that option will override only the current channel you're watching, and will then revert back to the option set in the Audio settings as outlined above.
