This will likely be no earlier than 1992 judging by the Robocop 2 clip seen in the promo. I think that film took about 2 years to premiere on Sky, many did back then due to the rental and retail video market, another 2 years later they normally aired on terrestrial TV once Sky had finished showing them.
What else was on the recording, ie what was the film shown next and at what time? such info wouldn't be too difficult to source the date of this recording if you have old TV and Sky listings. I have quite a few from the 1990s, so far from late Sept til Dec and some early Jan.
