OK, in which case you need:
A new video recorder, since your old one is kaput - good four head philips model, 30 quid, eBay
An interface between that and your PC - search for "video capture" - cheapest one you can find. I found 'Pinnacle DVC 100 Dazzle DVD Recorder', which has a capture device and software to go with it.
An awful lot of time.
You may find it more effective, if your time is precious, to buy a cheap DVD recorder (on top of the video player), rather than go through the interim step of recording to PC, then burning to DVD - all of this has to be done in real time anyway, and if you have forty three- or four- hour tapes.........
Note also that a three or four hour tape won't fit on a single layer 4GB recordable DVD, so you need to split the tapes or use double-layer discs (expensive).
Note that this won't work for prerecorded tapes - then you'd need a macrovision decoder and a clear conscience.
