New Samsung Tizen App Preview

The Roku App under Settings, Video has an option to support MPEG2 for Live TV. This helps avoid transcoding and a smooth experience on LAN. Would the Tizen App ever be able to support (hardware wise) this option and if so any plans to add it?

I am finding that without this option selected, it is impossible for me to view Live TV with all the buffering although I do have a somewhat powerful CPU Where is the buffering coming from on Live TV (stored movies are fine)?
