thanks for the update Bob,
install samba on machine 1 via the browser, package management. make sure it's running in service management, reboot if necessary.
you should be able to connect to machine 1 via windows file explorer, i.e. it should appear under network. If it doesn't type machine 1's ip address such as:
into the navigation bar and press return, i.e. where c:\users or ThisPC or similar normally is. You'll need to find the proper ip address as necessary.
What you should end up with is a list of available folders on machine 1, change directory to Video and copy over to your windows 10 pc everything you want to keep, don't copy the 0.ts and 0.nts
If you've reached this far then you have the choice of simply re-formatting machine 1 and copying back or attempting repairs to the filesystem. Most people I'd imagine would re-format and copy back.
