The easiest way to do this is not use a PC at all.
I have a video player and a DVD recorder linked to my TV.
I put a VHS tape in the VHS player, and a blank DVD disc in the DVD recorder.
I then press Play on the VHS player and record in the DVD recorder and the DVD is created.
Even if you want to do editing of the video image it is much easier to get the image OFF a DVD onto your computer than to get the image off the VHS tape into your computer.
Note also that VHS or DVD video takes a HUGE amount of room on your hard disk so you need to make sure you have loads of hard disk space.
