Hi everyone, I've just upgraded my amp to the new JVC RX-DP10VBK THX Ultra and am just having a few problems. When I use a DTS ES DVD the Amp automatically jumps to DTS surround and all the speakers on the amp are lit on the amps face/dial i.e L C R LS RS LB RB SUB I can use the DTS with the THX switched on if I like - no problem. Trouble is I bought this amp to play my DD Ex DVD's and I can not seem to get them to work, not one of them. That is they work with ord DD but I can not seem to get the DD EX to kick in and the LB and RB on the amp are not lit. Any help would be most welcome! Cheers Paulh.
