I've had occasion to view European TV in Europe, and I, too, can attest
that the 50 Hz frame frequency makes for some very noticable flicker.  I
think, however, that some TV makers to Europe are now putting frame
buffers in their sets and scanning at double frequency to try to make
the flicker go away.
