I think the issue is going to be your playback device.
I used to find encoding a DVD with proper 5.1 surround was the only way to go.
Now I can use 6 channel playback from Avid or Resolve, going through BM hardware, and then an SDI to HDMI converter, and then to the Amplifier and TV, but you need an amplifier that will accept that signal…they don’t all work that way. If memory serves, it has to pass through AAC audio or PCM audio or something like that.
I do always have to swap the center and LFE channels out of both Avid and Resolve, which I think might be a issue in the BM hardware.
What are you thinking your playback device would be?…how does it feed the TV?
Telestream Switch might be able to playback anything with 6 channels, through BM hardware to the TV. Pretty sure I’ve done that as well, but because of the channel swapping, I usually just use Avid or Resolve.
