Sometimes, when you play an AVI video in QuickTime, you may meet format incompatible problem like the above quoted words complained. That's not strange, because AVI is also in different codecs. Some types of AVI formats such as DIVX are not accepted by QuickTime. So, how to play these types of AVI videos smoothly in QuickTime?
