You can do this by following these steps:
- Log in to the My Account page on the IceTV website.
- Click on the "My Recorders" tab.
- In the bottom of the screen under "Add a Smart Recording device" enter a name for your device in the box marked "Device label" (e.g. Loungeroom or Vista or EyeTV).
- Choose the recorder model that you have.
- Click "Add".
- The page will refresh and you will get a confirmation message at the top saying "Device Added".
Additional devices can be added using the same method if you have more than one Media Center PC, Mac or PVR.
