There is a long and tedious way technically but it involves using 2 chrome extensions, developer tools, and lots of copying and pasting into the browser. There is a much and easier way here though (you do need to have kodi so this basically rules out certain devices including the Iphone (unless u root it). This is sadly the cost of them using drm it only hurts the consumers in a way like video games just not as much here since you still have a way to watch. This only hurts the technical consumers who want to watch it anywhere for pleasure. I don't really detest the DRM since you can find ways around it either way apparently. If DRM was everywhere I would be more mad since we should have access to recording older stuff in a more legal sense instead of having to pirate absolutely everything you want to watch.).

Anyways just use this guy's repo for kodi: https://www.matthuisman.nz/2020/02/slyguy-kodi-repository.html

Then you want to add the PBS addon from his repo. That's basically it.
