An Error Occurred Loading This Content - AppleTV - Youtube

When trying to view YouTube videos on my AppleTV, quite a lot of them give the error "An error occurred loading this content". However, if I use my Windows laptop or my 3rd Gen iPad (youtube app) then the video runes fine. I've searched this board for past comments and many of the responses were about problems with the source and that the source creator needs to fix this. I find this odd for two reasons:

1) this only happens on AppleTV with videos that just a month ago would run fine,

2) ALL videos that give this error are Christian Music videos from different independent groups.
