Hello first post and hope I can get some help.

Recently bought a 5.1 Blue ray home cinema works well but the audio isn't leading the video its lagging it.

On the home cinema you can delay the audio but I need to speed it up. The home cinema only goes to 0 at the negative end no - so I'm stuck. Have tried many times at trying to sync thinking it was the other way but I'm now sure the audio needs to be sped up.

I have a Samsung 46d5520. Unfortunately it hasn't got arc-hdmi so the home cinema is connected to the TV with a hdmi and an optical cable.

When watching a DVD or Blue-ray there is no sync issue but watching TV the problem is there and I'm stumped as to how I can resolve this.
