Query: Beware---Only plays on Windows 7

I returned the first copy of this title because it would not play on my DVD nor on my computer. Amazon sent a replacement. The replacement did not play either. It turns out that it only plays on a Windows 7 operating system--which we only have on our newest computer---I would have liked to watch this on our TV while comfortably lying on the sofa rather watching on a monitor while seated on a desk chair in my husbands office. I'm sure the film is great but it'll probably be a long time before I'll sit at a desk to watch it.
