As far as video is concerned, short of native Amiga animations, you're out of luck. MPEG, let alone Divx, is too much for a stock A1200.
Consider getting an accelerator as soon as possible.
Well, DivX is too much even for the fastest PPC-cards available for the A1200 (if we are talking about... uhm... let's say 'normal' sized movies with good quality).
Please correct me if I am wrong here, which I might be since I don't own any PPC-accelerator for the A1200 and never extensively experimented with any.
