The application is free, and allows you to play live and recorded content from your SlingBox.
Boxee is updating fast and furiously - at least when it comes to the Boxee Box. They announced the Live TV dongle for over-the-air signals recently and today they've added a new feature - SlingPlayer.
"For those who aren’t ready to cut the cord," writes Nick on the Boxee Blog. "we still want to help you shave your cable bill by never having to pay for the same content over and over." Thus, the introduction of the SlingPlayer app.
SlingPlayer allows you to play any content from your SlingBox on your Boxee Box no matter where you are in the world as long as you have an internet connection. You can access your DVR, cable box or DVD player from anywhere in the world and you'll get content streaming in 1080i.
