With your equipment I would connect as follows:
Aerial into DVD Recorder and from DVD recorder into TV. Bypass the VCR all together. (let's face it, your VCR won't need an aerial plugged in any more as you have a dvd recorder).
Then I would connect the VCR scart out to the DVD recorder scart in. That's the only scart cable I would use.
Your DVD recorder has an HDMI output and your TV also, another option is to connect via component, both methods give a better picture than scart, especially if the dvd recorder can output a progressive signal over the component connection (and a quick check of the manual states that it can). I wouldn't use any scart connection between tv and dvd as in your case both units are HD compatible.
