I setup my Pro with the HD Component cable to my XBox 360 today.  It works at all resolution settings on the XBox 360 from 480p to 1080i.  The cool thing about this setup is that it can view the WM9 HD content that you can download from XBox live or ATSC content that is recorded by a Media Center PC from its ATSC tuner.

 The video looks amazing; even at 3000kbps on the LAN.  To set this up do the following:

1. Connect the XBox360 HD Component cable along with L/R audio into the input jacks of the Sling HD Component Dongle, plug this dongle into the SlingBox Pro.

2. Connect a set of RGB component cables into the output jacks of the Sling HD Component dongle and then plug those into your HD TV.  You can use the L/R analog audio out on the Sling dongle or  the digital audio from the XBox 360 HD Component cable.

3. Place a SlingBox IR Dongle in front of the XBox360 dark tinted plastic IR window.

4. If you are a new owner of an XBox 360 HD cable, setup the resolution of the XBox360 to that of your TV.  My DLP accepts 720p, but the Sling hardware will accept any of the three HDTV sizes automatically (no settings are required) for 480p, 720p and 1080i.  Do this under the System, Console Settings, Display blade, HDTV settings.

5. For the IR remote capabilities, under System, Console Settings, Remote Control (second from the last option) select All Channels.  This allows you to use the IR Blaster for the SlingBox with the XBox360, or any Media Center remote control.

6. Within the SlingPlayer, under Slingbox then Properties (ALT-E), then Slingbox Configuration then Audio/Video Setup; configure the SlingPlayer to use the Component input and choose DVR then Microsoft/Media Center as the type of device.  The model can be Media Center or Other.

7. Connect the SlingPlayer to your SlingBox Pro and choose the Component input.  You will now be able to control the power and navigation on the XBox360 blade system.  Enjoy stored video clips and even use this as a Media Center Extender remotely!

Now you probably won't be able to "Gameshift" or play many games as they look for an attached joystick, but you can view the demo trailers and any multimedia content on the XBox hard drive or any other PC's on your network.  As developers add IR remote support for their games, you may have some luck, but the network delays are going to make you slow to the draw.

 Enjoy the hack!  If you get "stuck" in a game that "Back" doesn't work in, cycle power or use the Media Center button on the remote to exit the game session.
