due south dvds?

I need help from the DS fans! I'm looking for the Due South dvds on Amazon.com, but after reading some reviews, I'm confused! Season 3 is the season with RayK, right? And is S3 split into two dvd sets? Or can I just buy this set and it should have all S3 eps in it? (And this is the right S3 set, yeah? Confused me because RayV was on it and not RayK....) I also read that this final season is basically the previous S3 epsiodes/dvds I linked? Are there any missing episodes, because I read the American version had some eps cut out.

Thanks guys :)
