I thought I should highlight this.
Some of the lower end BR players no longer do internal decoding of DTS-MA. Some don't decode True-HD.
Does this affect you?
Well that depends. If you have an up to date amp, there is no issue if you are using the amp to do the decoding. Just send a bitsteam signal to your amp and you will still enjoy True-HD and DTS-MA.
The issue comes when you are trying to apply DSU to your DTS signals. Then you will need to send a LPCM signal to your amp for DSU to be applied. This is a flaw with the 2015 models, and does not affect the 2014 models. Well, at least until the DTS-X update comes into play. Then the two models which can be update (Denon 7200 + Marantz AV 8802) will also be affected.
Not sure what is DSU / Atmos / Dts-X ? Check your amp first, you may not be running this and you won't be affected at all and can continue to enjoy your 7.1 or 5.1 systems.
This only affects the new 3D sound formats.
