@joeral and @jason We have added a first cut of experimental support for this in build 4307. You can choose up to 6 channels of audio to encode now to a BluRay iso file. Its still encoding as MPEG2 and the audio is LPCM. We have tested this on a few players here and it seems to work.
Give it a shot and let us know how it goes on your end.
Two notes:
- Trying to encode a bluray with an odd number of audio channels will cause the packaging to fail
- Trying to encode a bluray with 8 channels of audio causes packaging to fail too.
Stick to 0, 2, 4, or 6 channels for now.
