VHS to PC

Hi, I've searched through previous threads prior to posting this and while there have been threads on this I was wondering if anyone could help me as I wanted to know if I could achieve the above without the need to purchase more hardware or software.

I have a standard (old) VHS video recorder, a Pinnacle PCTV DVB-T Stick (72e) USB TV adapter and a Fujitsu Siemens S Series Lifebook laptop running Windows XP. I also have Pinnacle TV Centre Pro and Nero Vision software. I have connected the VCR to the laptop using coax cable going from the VCR to the USB TV adapter and the adapter into the laptop via USB.

With the above, is it possible to capture VHS to my laptop? If so how would this be done? I really have no idea.

Many thanks in advance...
