I don't know what part of the world you're in Karl but Pinnacle have a reasonably cheap PCI capture card out now I think it's called the PCI 500 (someone correct me if this is wrong) and it has both analog video and digital video capture available on it. You have to capture analog video through your sound card. Check to see how much that 'company' you mention charge or maybe it might be cheaper to buy a DVD recorder from a store like Argos or Dixons if you live in GB.
