A media content presentation system extends other devices' capability of sharing media content via a presentation device. A computing device, if coupled to a plug-in device of the media content presentation system, can present media content via the presentation device. The computing device provides the media content to the plug-in device via a proprietary communication channel established by the plug-in device. The plug-in device then passes the media content to the display device for presentation. The display device receives user input and provides the user input to the computing device for adjustment of the media content according to the user input.
