The feature works perfectly fine with my Roamio Basic. The XBOne decodes the DD multi-channel audio and outputs it in multi-channel PCM. What MS need to fix is the output. Right now the output is fixed, not dynamic like it should be. So if you have the XBOne set for 7.1 output, and 5.1 content from an app or from the HDMI in is output in a 7.1 wrapper with two channels dead. So no post processing can be applied. With stereo content it's even worse since all channels are dead except for the FL and FR channels. Without manually changing the output channels to match the input channels, it's like watching TV was decades ago. When you only had stereo like in the 80's or a 5.1 system like in the 90's. To have the proper output, the XBOne needs to dynamically change the number of output channels to match the number of input channels. But even the PS3 and 360 never got this right all the time. They still had issues with some apps doing the same thing, while other apps dynamically changed the output like it's supposed to be.
