I have a Sony and Denon AVR = no support for DD+
I have a Philips and Sony TV = no support for DD+
I have a SONY 32" LCD TV bought 3 years ago, when there were no DD+ broadcasts in Spain.
I have an LG 19" LCD TV bought 2 years ago when there were no DD+ broadcasts......
Both get DD+ perfectly, and firmware hasn't been updated.
DM is 5 months old......
