Review of The Awakening Land

I have seen this movie every time that it has come on TV and wish that I could purchase it on DVD. Does anyone know why it isn't available for purchase? The story of Sayward and her family is amazing and completely well acted by Elizabeth Montgomery and Hal Holbrook! Someone please do something so that we can see this important work again and again! I taped it once on my old VHS machine when it came on TV but my sister overwrote the video! I didn't speak to her for months after that! If it ever is released, I will be the first in line to purchase it. Is it NBC or Warner Brothers who is holding up the release of The Awakening Land on DVD? I've read the books but it just isn't the same as the mini-series. Being a native of Illinois, I really like that the movie was filmed here!
