Difference in transcoding between DVR and Live TV

Why does my Plex server transcode Live TV, but it takes the native (already transcoded by HDHomeRun Extend) format when recording to DVR? I would like Live TV to take the transcoded format from the HDHomeRun Extend and just send it to the client for viewing.

Is this something that is being addressed with Live TV and will show up in an upcoming version?

Thanks, Jim

Comments anyone?
