You can buy firewire pcie cards on Amazon for $20 that work with windows 10, then use win dv to capture, works great with d8 and dv.

I've heard of d8 camcorders that are v8 compatible but never seen. V8 and hi8 I just use rca.

Blackmagic digital studio capture cards work very well.

No matter what you do all these old formats never look good imo.
