Thanks a lot for the feedback. Very interesting!
Just to confirm, you're saying, unlike the other poster and I, you're able to play Dolby Digital D Plus (5.1) Netflix movies on the Roku with the Netflix audio set to 5.1 (go into the movie options for that particular movie to ensure that it is not set to stereo) when using an HDMI switch (if you could test it without the switch, if not too much effort / trouble, that would be a good test).
If you are getting both 5.1 audio and video from Netflix DD Plus movies via the Roku paired with the R-972, that is great!
Perhaps the switch is acting as a problem solver, in effect, by handling the HDMI handshake from the Roku and then passing it onto the R-972 which the Newcastle can perhaps then handle, unlike it coming directly to the R-972 without the use of a switch.
Too bad I lost the power supply for my Kinivo HDMI switch! Otherwise I could test it myself tonight.
