Hi, This could well turn out to be a stupid question so please ignore my ingorance. I have Yamaha RXV800RDS amp, and a Warfedale 750 DVD. Now I'm under the impression that all of the Warfedales have DTS, is this true? My probelm is this, I endured Fast and Furious last night but couldn't get DTS sound. If I selected DTS on the amp I just got silence. I am using CO-AX digital connector to the amp in to the SAT/CBL CO-AX input, and have remapped that input to DVD. Could this be a reason for no DTS? Do I have to use the optical link for DTS to work? Or is there anything else I should be doing? Do I have to tell the DVD to output in DTS mode? Any help would be appreciated. Yours confused, Jezz.
