Not sure what exactly you're saying here.
If you're saying "Why doesn't SlingPlayer for iOS work with [any flavor of] Windows?", they're completely different even though they seem the same. The same reason one can't take the engine for a semi truck and install it in a car.
If you're saying "SlingPlayer for iOS works on OS X, why doesn't SlingPlayer for Windows Phone work on Windows 8?", SlingPlayer for iPhone nor SlingPlayer for iPad work on OS X.
