Interesting. When I saw the other uncensored video, I was like "WTF ? How they didn't censor it rightaway".
There must something weird behind it, because I know only one VHS release (from Pumpkin Pie/Alice Japan, see attachment). Or there are "bootleg" versions of this too.
As it is censored, it's not really important to have it.
It is maybe the same story like Cream Lemon 1 & 2, where the first VHS editions went accidentaly uncensored, according to japanese Wikipedia. That's why you can find completely uncensored versions of them, but with an awful video quality.
For red and others, the most widely known versions are a 250,035,320 MPG file (part 1 only), and a 605,884,416 MPG file (both episodes). In fact you can even see that it was edited from two different sources of slightly different quality.
