Before connecting your Xbox 360 to the HD-PVR, please make sure it is set to the proper video output setting by connecting it to your HDTV. By default the Xbox 360 will be set to 1080p and the HD-PVR will not work with this resolution. You will need to change your Xbox 360 to 480p, 720p, or 1080i.
Please turn on your Xbox 360 to the main menu.
Navigate to the last menu on the right and go into System Settings.
Go into Console Settings
Go into Display.
Go into the HDTV Settings.
Now select the resolution you want. The HD PVR will only work with 480p, 720p, and 1080i. If your system is currently set to 1080p change it to 1080i.
When you select the new resolution, you will be asked if you want to keep the new settings. Please select Yes, keep these settings.
You are now done. Please turn off on your Xbox 360 and connect it back to your HD-PVR using component cables.
