While Plex supports the above formats, the clients you use to play your files must also support the formats. If a client does support the format, then Plex will direct play the file instead of transcoding, or direct stream, the file to the client.

The best solution would be to have Plex direct play as much of your content as possible, especially for movies. There is a simple method you can use to get Plex not to transcode movies very often.
