Well you need to think of it more like TV1 and TV2.. not tuner 1 and Tuner 2 since there is no such thing as a OTA output on the 622.
There is a 622 composite output on the 622 that you could hook up to your TV1 and be able to see what is on TV2 and what is on TV2. However the composite quality will be nothing like your component or HDMI output.
There is no way to get HD outputs for both TV1 and TV2.
