Cannot remove existing audio stream from video file

Hi…
I get this error message. I have seen people have this issue in the past but I haven’t been able to find a modern solution given the Cubase video engine got upgraded.

what causes this issue and how can i fix it?

(trying to replace audio from a video)

thanks

Well they removed replace audio in video file.

But the audio can still be extracted from video on import (except on WIn7)…if this isn’t working maybe the video is an unsupported format?
