The amount, quality and nature of digital media depends on the bandwidth (data rate) of the delivery mechanism. By choosing content carefully then adjusting rates, size and quality, you can produce good-looking multimedia. Just be sure to test early, test often and test on target platforms (the Macromedia tech support mantra).
