Obviously, you didn't look at an european TV, which has a MUCH better quality than NTSC (except when they brodcast american serials :-)). Moreover you are forgotting the fact that movies are at 24Hz, and no mortal can see them flicker!

Seriously, this IS the point, and we have the same problem here: just as your room is filled with 60Hz electromagnetic waves, my room is filled with 50Hz radiation (HiFi, TV, fridge, electric heater, lights), but the biggest source of "noise" is the amiga power supply! I was able to have a nearly stable NTSC display by just moving away my A500 power supply (but how do you do this with a 2000??) -- Colas Nahaboo, colas@sa.inria.fr, Bull Research, Koala Project, GWM X11 WM Phone:(33) 93.65.77.70(.66 Fax), INRIA, B.P.109 - 06561 Valbonne Cedex, FRANCE.
