SFM Entertainment has the distribution rights to the show, but a check at their web site shows only two 4-episode releases from Rhino.

Maybe this was a deal that was supposed to happen and didn't or, perhaps, it's still in the works. Judging from their TV-on-DVD releases, if "The Real McCoys" does get a season release, it would likely be done through an independent. Looks like Questar, Rhino and S'more Entertainment have all released SFM properties.
