Aiwa HTDV90 Hi,

Can anyone help?  I have an Aiwa HTDV90 home theatre kit and it is having difficulty reading DVD (error - NO DISC).  I was thinking of buying a new DVD player and using it for the video and I was hoping to find a way of connecting this to the HTDV90 to use it as an audio amplifier.  Anyoner got any idea of how to do this.  Aiwa weren't too helpful and told me to use the stereo RCA jacks.  Not much point in having 5.1 if you don't use it I feel

Thanks

Terence
