|There are several ways:|
1. Buy a device (like a camera) that plays it, output through RCA cables to your other camera or tape deck that is digital through the line in, and then just record that. (Alternatively, you could put that signal into a DVD-R machine and record onto a DVD, then just copy the files off the DVD, if you don't have a way to capture DV through firewire.)
2. Buy a device that plays Digital8 (same tapes, but miniDV FORMAT) and output directly from the tape through firewire. This means you must buy a SONY (only brand that made [now discontinued] Digital8) camcorder or deck [if decks were made, though those are usually expensive].
