I would have said composite is always bad. Composite fits colour and
brightness next to each other, the colour modulated higher than the
brightness signal.. When there is fine brightness detail on the
picture, this increase in bandwidth affects the color signal.. Have you
not seen the effect of looking at a pin stripe suit worn by a weather
person? Under a composite signal you *might* notice that the suit
changes colour rapidly and appears distorted.. This does not happen
with Svideo or RGB.. it is a side effect of composite.. *shudder*

IMHO composite is to be avoided where possible, though I am using it at
home, until I get round to buying a longer Svideo cable :)
