Hi, Can anyone help with this one pls. I have a Panny SCHT1500 all in one DVP/Home Cinema System and a PV500 Plasma. Whenever I press "Display" on the DVD player I see the above information for the DVD sound track even though the DVD disc box says that it should be Dolby Digital 5.1. Does anyone know why "Dolby Digital 5.1." doesn't appear? Thanks in advance.
