Did SSR recently get a TV upgrade? Because IME they do NOT have the separate input box. They are tube TVs with RCA inputs on the front (red/white/yellow). The only resorts where I've seen the separate input box are those with flat-screen, HD sets.
The tube sets also have inputs on the back, but they're also 3-jack RCA. The resorts with flat-screens with the input boxes offer USB, HDMI, RCA and maybe just sound? I don't recall exactly, but I do know on the back of the flat screen there are also 5-jack component inputs.
