Well getting the audio through JRiver is half the battle because I wan't to move my DSP FIR filters from miniDSPs into the PC. But I also wanted the video to go through JRiver so I can maintain lipsync as my filters have appreciable latency.
As it stands now, I open the Netflix player in JRiver as connected media, which seems to be just like in a browser, and I get the audio but not the video. I see the cover art and early screens but once it starts playing the display goes blank while the audio continues. But even while the main display is blank, if I touch the timeline at the bottom with the cursor I can see a mini preview screen.
Trying to repeat that process now to describe it better, I keep getting an error
"Whoops, something went wrong" with error code H7053-1013
And the other funny thing is that everything else works. I can see YouTubes and play Amazon music and play DVDs from the computer's optical drive. I just can't see Netflix except when viewing them directly in the browser without the intercession of JRiver.
