The trouble with using a computer to do it is it uses a lot of processing power and takes a hell of a lot of drive space.
I'm not sure you can connect a VCR to a firewire port.
To be honest with you the simplest way is to take the computer out of the equation in my opinion.
Get a cheap standalone DVD recorder and connect that via the SCART lead to the video, set it up correctly press play on the video and record on the DVD and job done. You might need to finalise the DVD but the manual for your DVD recorder will explain all that.
Its a lot simpler than other methods, in my opinion at least. Of course you can't edit them doing it this way but it is easy.
