I successfully installed most of those (instructions here: https://support.plex.tv/hc/en-us/articles/201187656-How-do-I-manually-install-a-channel-), but none of them worked. No access to any video content.
I tried:
- ITV-Player.bundle
- 4oD.bundle
- IceFilms.bundle
- LetMeWatchThis.bundle
- DemandFive.bundle
