I've seen the 1992 Japanese film crew clip a few times on a syndicated Freeview channel - the last time within a year or so ago. The clip is in the
second episode (Spirits of the Forest) of a three-part documentary on the nature and wildlife of the Congo produced by the BBC (2001). You can find
out more at the following link:
(If the page doesn't show, just search for 'BBC Congo' in Wikipedia and you'll find it.
The second episode is summarised thus:
2. Spirits of the Forest
The Biaka (Bayaka) and Baka pygmies of the northern Congo basin relate tales of the Mokèlé-mbèmbé, a legendary, dinosaur-like creature purportedly
inhabiting the Lake Tele region of the Republic of the Congo (ROC). It is thought to feed on Landolphia, a type of liana. More mundane denizens of the
ROC include moustached guenons, crowned guenons, red colobus monkeys, okapis and the blue duiker. Figs sustain great blue turacos, black mangabeys and
various hornbills. The forests of Tanzania’s Gombe National Park support common chimpanzees and the bais of Dzanga-Sangha National Park in the
Central African Republic support numbers of forest elephant. Other Congolese inhabitants featured include red river hogs, bongos, forest buffalo,
orb-web spiders and colonial spiders. Returning again to the ROC, the Biaka are seen to expertly craft Portuguese-style crossbows and arrows made from
seven different kinds of wood and other plants. Gorillas are again viewed at the Odzala National Park.
The re-runs would probably have been on the Freeview BBC3 or BBC4 channels.
The BBC may still hold copies, or be able to tell when if/when it's likely to be re-aired.
