Basically when capturing to a PC you just want the cleanest video path possible. The V8000 has pretty much a straight through video output, it is one of the hidden gems of the laserdisc scene.
It isn't something that you could point to and brag about in your lounge room though, it is big noisy and ugly and has almost no features. For a capture project though the lack of features is a distinct advantage, there is less circuitry adding noise and creating loss on the video circuit.
