Thank you for posting to our forums! That's a great question! There is not yet a SlingPlayer application for any Smart TV. We do not have an ETA on when there will be an application for one of them. However, I would recommend using a Connected Device. An example would be a Western Digital TV. It is a streaming player that connects to your TV via HDMI and has the SlingPlayer application built-in to it so you can stream from your TV.
Below is a link to a page on our site that explains SlingPlayer for Connected devices:
Hope this helps!

Samsung Smart TVs may not have a slingplayer app built in their TVs, but I just saw where the JVC SP500-C TV has a slingplayer built in, and I am wondering if anyone knows which other TVs also provide the slingplayer app, or where I can find this info. I have a Slingbox 500, and am interested in buying a new TV with this feature. (The JVC is a little large for me (50")).
