if you want to try with fb, add this to your /etc/fb.modes :

mode "tv"
    # D: 49.188 MHz, H: 46.580 kHz, V: 75.008 Hz
    geometry 768 576 768 576 32
    timings 20330 128 32 32 8 128 5
endmode

and invoke "fbtv -m tv", note that the interlace effect remains...
but __perhaps__ it will be less evident.
A filter will be the best solution.
