That site, especially the non-store part, does not looks very legit or at least it does not give very good impression. Personally I'd say those DVDs available at the site are unauthorized copies and are there without the consent or the knowledge of the rights holders. One of the biggest warning sings of non legit DVDs usually is that sold DVDs are region free as mentioned in their FAQ (obviously not always as there are also legit DVD-releases that are region free).
