What is the Best Format for Playing Videos with Plex?

Jason is ripping DVDs and he wants to know how to convert them to use PLEX on the Roku. Leo says to convert using HEVC H.265. While it won't give quality better than the original, it will look as good as it can get. To encode, Leo recommends Handbrake.FR and VLCMedia Client. Regardless of what encoder Jason uses, though, he should make sure to use HEVC H.265
