Hi Everyone, hope you can help. I've recently purchased this DVD player and after connecting to my 5.1 home cinema system the sound is only coming through as stereo. Connected the co-axial cable from home cinema to dvd player. Connected hdmi cable from dvd player to tv but when entering the audio set up option for the dvd player i am unable to select the co-axial/digital out option as it is shaded. Why ?? Only the analogue output option is available. Really annoying as i want to experience the full HD and Surround Sound experience. Any help / advice much appreciated.
