You need to plug your lead into the VCR scart socket located at the bottom of the V+ box and plug the other end of your scart lead into the AV scart input on your DVD recorder.
I've got my V+ box hooked up to a DVD recorder and i can either record directly from Live TV or the copy to DVD/VCR function which is better as you can record 2 channels at the same time and watch a 3rd channel all while its copying to the DVD
