Going through the Japanese LD from 1986 that SilverWook sent me a capture of, just like the '82 Betamax, you can see that the Buck Rogers segment appear quite close in its colors to the '04 DVD. So that's basically the timing I will go with, if you don't mind.
They squeezed the opening titles for this transfer, if only the cropping had been better it would've been an even better alternative than the DVD titles, damn!
Another interesting thing is that this release was censored just like Skyjedi mentioned could be the case earlier in the thread.
EDIT: Sorry, ImageShack don't like women's breasts. ;)
^^ I find this one pretty funny as you cannot even see anything in this shot. See the pixelated area.
From wikipedia:
"In Japan, it is illegal for any commercial work to display the human vagina and phallic in an explicit manner. Any publications depicting the penis or vagina must be shrink-wrapped and barred from sale to minors. However, it is not uncommon for pictorial magazines to depict nude women with their genitalia airbrushed over in black, and video pornography routinely depicts explicit sex scenes with the participants' genitalia mosaicked out. Until 1991, the entire pubic region, including hair, was deemed obscene and unpublishable. Recently there has been a diversification in the censoring market with there now being several companies which offer it. The government's sexual watchdog group is still considered to be the more harsh though this in many cases depends upon personal taste as most of the companies practices vary, with some opting for the more controversial (as opposed to the mosiac) big black bar. As of now it looks as if the censorship laws will be lessened due to the Internet's pervasiveness and the underground pornography movement which began in the late 1980's. However, it still has a large number of followers in the society as a whole and regardless of opinion it has become somewhat of a "cultural practice". An example would be that even though pubic hair is no longer illegal to depict, many AV movies still frequentlly censor it and hentai art and films do not usually even have it drawn. This has led some, predominantly westerners, to view Japanese pornography as being somewhat pedophiliac and seeing many of the females as being younger than they really are intended to be."
