I have found that it is getting increasingly difficult to sort through all of the various DVD versions that are out there for a single title. I usually buy used DVDs and it is hard to know whether the version I am buying is the original, the directors cut, the enhanced, or the special anniversary version. For instance, today I bought "Unforgiven" for $8 which I thought was a great deal. I didn't know that there was more than one released version. Is there a Web site that can help a person sort through the myriad of DVD versions that are out there?
