From stackoverflow

• Looks like you don't have the DivX Decoder bundle (DivX Decoder.component) installed in your other Mac.

  I checked on my mac, and I don't have it either, so it something you installed on your own.

• Looks like the DivX codec isn't installed on that other mac. Install DivX and you should be all set.

• Actually you do have DivX, but it's missing a symbol, and you need to delete /Library/QuickTime/DivX Decoder.component
