I just got my spring classics DVDs from WCP and plopped down on the couch to watch Paris Roubaix and was quite pleasantly surprised.
I believe prior years' DVDs were produced from SD quality source material, the 2007 edition appears to be derived from HD source material. The picture is not HD, but it is as clear as any widescreen DVD I've seen.
The color of the peloton pops. It's a great visual feast compared to the fuzzy images presented by Versus and cycling.tv.
