I have a video with 5.1 uncompressed multichannel audio and I don't want it reencoded. I don't want the audio altered in any way. I just want Poweriso to create an ISO file of it so I can burn it to a Blu-ray disc.
I suggest you ask this question on AVForums' Network Video Streamers forum where there are lots of experts familiar with this stuff. https://www.avforums.com/forums/network-video-streamers.332/ JB
