The following website is of interest to French Young Indy fans (has links to the unaltered French VHS releases!). I haven’t provided a direct link, should this break the rules.

Thanks for the info.
I’ve checked the first 3 episodes out and it turns out that they’re digital SD TV caps from France 4. I found a link on the France 4 website so they must still show it https://www.france.tv/france-4/les-aventures-du-jeune-indiana-jones/
The videos have a logo bug in the top right corner and the on screen text is all in french but overall very good quality.
