Yeah, that section needs to be rewritten. We have no TV modulators at all.
If a video/vbi node supports G/S_MODULATOR, then it is a TV modulator. If
a radio node supports it, then it is a radio modulator.
Even for g/s_freq and g/s_tuner the type field is now determined strictly
by the type of the node. It is no longer possible to e.g. query the radio
tuner from a video node. It used to be possible (as least in theory) in the
past, but that was crazy.
