But it doesn't show neither video nor audio. When I reboot to Windows on the same drive, everything works okay. I have tried with VLC, SMPlayer, mplayer, Flowblade, Pitivi; nothing to be seen or heard. What can I do next to progress, please?

I did a web search and found quite a few things. However, some are rather old but seem to be mostly the same. I'll give you the web page, but I honestly do not know if this will help you or not. Hopefully someone else will jump in here.
