SlingPlayer is showing up all over the place lately — it just hit Facebook and Chrome last week — and now it's coming to the Boxee Box. The new app is the first of Sling's apps for connected devices strategy, and it does everything you might expect: owners of a Slingbox Solo or Pro-HD will be able to remotely view and control their DVRs, and Sling's touting a revamped program guide that it says will streamline navigation. The app is also a nice way for new cord-cutters to still make use of their parent's cable if network programming won't be enough.
