I have a Sony Bravia TV connected to Sky HD via HDMI cable. The Bravia TV is also connected to a Sony DAV-DZ111 DVD Home Theatre System via a SCART cable. However, I can't play TV programs via the Home Theatre System.

Do I need additional Cables to connect between the TV and Home Theatre Systems to enable TV surround sound programs to play via my Home Theatre System?

Any help or advice would be appreciated,

Andy.
