Ed,
Just to round out what Martin said about the safe frame, its used primarily in
Video, as different home television sets underscan the video signal, the safe
frame helps crop the animation so that when it is broadcast, even on really
cheap T.V's, titles etc. are not cut off. Don't think its something you need to
be much concerned about. At least not for the time being. Course you start
adding some flying logos to your particles systems and you may end up on T.V.
yet. <BG>
