Back in the days bandleaders or people in their circle would sometimes sell the same footage to 2 or 3 different producers.
For example Werra's Kora of 2005 had two different DVD's
rehearshal at zamba playa (with the presentation of Anya Star), images of Kora Awards and a concert in Camp Luka to present his trophee to his "ba mpangi ya buala"
playback of ca sonne (for whatever reasons, somina was like monde arabe taking long to release the clips of temoignage), footage of Werra's triump and performace at Kora, rehearshal at zamba playa and the rest being clips.
Because of that I was wondering if it wasn't creating any conflict between producers. Apart that of filming in concerts. Back in those days you also sometimes an official VHS/DVD of an important concert in Kinshasa, Paris or Brussels but then also a different DVD/VHS being released but filmed from a bad angle. It has been said that Koffi Olomidé had nothing to do with the way Marc Tabu got beaten by bodyguard Tony "Mukumbusu" Osvaldo, but that it was Manu Luvaka who sended him because of not wanting anyone to film in his concert except his own team crew
