Rating: - Nice for hardcore fans, but otherwise unnecessary
This is the CANADIAN season four of Due South. If you bought the AMERICAN season three, the one with Ray V on the cover, you have every episode on these disks. I rented the American DVDs before I purchased the Canadian DVDS, and it is true that the Canadian set has better quality video, but if you buy the American version YOU HAVE NOT MISSED ANY EPISODES. Even episodes that weren't aired in the US are included. The reviewer above, orchid1831, is incorrect.

However, there's a commentary extra by Paul Gross on the series finale that isn't included in the American set. Also, the packaging isn't as bad as some reviewers of the season 3 set have made it out to be. The overlapping DVDs are a little annoying because if you want to get to the one on the bottom, you have to pop both of them out, but the disks aren't "difficult to remove without damage" or anything. Perhaps if you tried to grasp the disk by the edges and pull it out of the case with brute force you would damage it, but there is a little button in the center that says "push" and magically, when you push on it, the disk is released.

I don't regret my purchase, but if you aren't worried about the picture quality there's no reason not to save money and buy the American season 3 instead of the Canadian seasons 3 and 4. Personally, this was my favorite season, so I am happy to spend extra for the quality and the commentary. If you decide to get the Canadian season 3 and season 4 instead of the combined US version, look for season 3 on the Canadian amazon.com, listed at the bottom of this page under "international sites". It's much cheaper than the imported season 3 offered on this site.
