Here’s a list that will help you decide which ones you might want to try out. The basic app is free, but you can upgrade to PLEX Premium ($4.99 mo, $39.99 yr, $119.99 lifetime). This lets you watch and record live TV on your computer or in the cloud (antenna and tuner required, as well as the ability to sync your content with compatible mobile devices). Similar to YouTube and Instagram Video, Facebook Watch allows you to watch user-generated video on your big-screen Samsung TV. The videos are grouped into easy-to-navigate categories which include Live Videos, Videos You’ve Shared, Videos Shared by Friends, Videos You’ve Uploaded, Videos from Pages You Follow, Facebook Watch Originals, and more. You can also watch a lot of live news feeds from sources such as the LA Times, Bloomberg and ABC News, as well as live gaming and some live sports. Doesn’t duplicate HBO’s live cable feed.
