Original DVDs are so one sided.....

Been to JB after many many years. There I was wanted to buy DVDs that is not avaliable locally. Found that there are many selections but most are not original so it is not possible to buy back. Just wonder how come they don't have the original version? What pissed me off is that their non original versions have different dubbings. If the original sold locally have such different dubbings would be wonderful. Guess I will have to search the net for such original versions.
