To Use my PVR card or FIREWIRE Port ?

Good Day Folks,

Here's what I want to do;
I want to take the video out of my Sony D8 & put it into a DVD.
I have the following:

Sony D8 Camcorder ( S-Video Output, DV Output & rca output)
Pc equipped with PVR-250, firewire ports.

I think I will use NEROVision Express 3 UNLESS ANOTHER PROGRAM IS SUGGESTED TO GIVE ME A BETTER QUALITY OUTPUT.

Basicaly I want to know if It's better to send my signal in my FIREWIRE PORT or into my PVR CARD ? Also, Whick Proggy to use.

Regards,
Dan
