RTMP should work on AIR for TV. This is a known issue and we are working with Samsung to fix this. They should be releasing an update to there products which fixes this issue. (Sorry I can't give a timeline, you will need to talk with Samsung about when they will update there TVs and Blu-ray devices).
Thanks for the info.
Good to know that this is just a bug and will eventually work. Will follow up on the Samsung forums.
