I would have converted other PAPA videos myself but I never saw on their website or elsewhere any license to share/re-distribute. So, I did not bother. Stream directly from YT would at least be a safer solution, but straight playback would be either severely letterboxed or really distorted from stretching to fit. If there is a standard format for the source video and how it should playback for people who use either portrait or landscape orientation then it may be possible to insert a filter to get playback looking OK. Not much that can't be done with perseverance but, myself, I've got too many other tasks on my plate at the moment for this.
