Sometimes a video file you are watching is slightly out of sync with the audio. This can be very annoying but is easily fixed.
Step 1. Whilst playing the film/video press the ‘ok’ button in the middle of your remote to bring up the selection menu at the bottom of the screen like below
Step 2. Scroll across to the right and click the ‘speaker’ icon
Step 3. You will see a pop-up menu. Choose Audio Offset
Step 4. Use the slider to put the audio forwards, or back. This can be done whilst the video is playing to see real-time results
Step 5. When you are happy with the sound, press the ‘return’ button on your remote, then return again to get back out to the selection menu.
