You're going to need an Analogue Capture Card - most TV cards have this facility. Leads will be dependant on the card, but normally come with it (or those with your camcorder will probably fit). There'll also be basic capture and editing software with it - all for well less than a ton. Do consider a DVD writer with your system - you'll not be too impressed with Video CD quality and many DVD players have a problem in reading VCD.
Do a search on this site - there's loads of threads on this subject waiting for you.
