richms:
I was using the xbox last time. It was probably them mangling things into that bastard 25FPS rate causing the problem. No idea why that persists in the post analog era, but the audio was bad 2 channel. I could hear artifacts and it had clearly had dynamics removed from it. Same show from the bay was a much nicer watch and listen.
I used TVNZ On Demand via a Browser on Linux and via Kodi on a FireStick 4k. Neither of them have the audio issues you report, but I'd love to see 1080 or higher bitrate 720p streams available.
