That's fine if you are careful not to overdrive a line level input
with transistors rated at 350 mW with a signal that is often higher in 
power, especially tv commercials (which are compressed and sent at maximum
allowable volume). Most line level inputs are 10K impedance or more, and
most headphone jacks on tvs are connected to the output of the power amp
and not through a seperate headphone amp. It is usually easy to tap in
before the driver or power amp and run that signal to the reciever or
pre - amp. It is also best to capacitor couple the signal -- never know
what dc voltages might be present, and not all pre - amps have capacitor
coupled inputs and outputs.
