Removal of AVI across all assets for normalisation, also the mediainfo FileExtension_Invalid I’m reading as a pointer that it needs to be alternative to AVI?

I’ve been made aware that the .dv choice only supports a stereo pair and that this might be the problem.  It’s passing one channel but it’s wrong and the audio is mute on playback. 

Might move to an MKV option to normalise assets as I see that dv was a bad choice. Will MKV work for dvcam?
