I just received the Sony remote commander and got everything working. Grandma uses a Joey, I entered code 3010 and the remote recognized the Joey without issues.
The instructions come with a list of codes for both TVs and sattellite receivers.
This remote is about a simple as it gets. A large easy to read keypad, volume and Channel buttons. The volume control will still work with your TV even if the remote is in cable/sat mode.
You won't be able to do anything fancy with this remote, basically enter your channel and control the volume.
The DVR and guide feature won't work.
Grandma is pretty happy so I would recommend it to anyone that needs a simple setup.
