| I'm on with a similar project for a colleague at work. Fortunately I have a Philips DVD recorder so I have linked up a VCR to it by scart lead to do the copying. I have then been using my PC's software to tweak the recording.
If you want to link your VCR to your PC then you will need some sort of video capture device.
May be a good time to jump on the DVD recorder band wagon. (Even Dixons are stopping selling VCR's). Cheapest I have found is Richer Sounds trade counter @ £89. |
