The legacy drivers will install and run under w10 but you still need a firewire card installed in order to connect to DV camcorder. I have the legacy drivers but cannot retest as camcorder has failed.
Not sure where the virtual drive fits in. Maybe try running virtual XP, it should work.
I had to get HDV off of a camera tape just a couple of months ago. Worked fine... already had a firewire port on my Windows 10 computer. Used HDVSplit software for the capture. Still works fine AFAIK.
I still have a mytek 8X192 adda with a firewire interface and use Syba SY-PEX30016 adapters in my win10 machines... had to download the Microsoft Firewire 1394 Legacy Driver Installer to get them to run. Also use them to transfer HDV tapes from an old Canon camera using the video capture included in VP.
