Two different versions?
So I was thinking about buying the DVD if I could find it really cheap, but on Amazon, there are two different DVD versions. I was wondering if there was really any difference?
The first says rated R, 87 minutes, $9.99

The second says Unrated, 91 minutes, $7.98

Is there actually an unrated version? I can't find any info on it.
