Thanks, yes. I am a happy customer of Amazon video which I watch through my Samsung TV as well as a Roku.
A lot of the facebook content is short pieces ripped from other places. What bugs me is that the ones I want to watch, mainly news clips, have no captioning even though I know the original source was. And from the clip there is no way generally to back to the exact source point. It seems facebook is re-hosting the video content (which in itself seems a little dodgy, but…).
