I am fairly new to this av lark and have a probably amusing question. Laughing out loud is permited. My pioneer vsx810 is a few years old now and looks as though it no longer wants to output dts audio. Pioneer have said it may need repairing as an internal bit has possibly passed away. Is it possible to have the internal parts upgraded or is that just stupid. My amp decodes dd and dts-es but not dts 96/24 or dd-ex and is 7.1 compatibale. Any comments of my tight purse strings are welcomed.
