I've had this problem running AVI's in quicktime. There is no Audio. I have downloaded several different codecs for this, one which has actually made the AVI viewable, but after my efforts, there is still no sound. I am running Quicktime 6 I've downloaded the 3ivX D4 4.5.1, i263 decoder, and indeo video 5 extensions/codecs. As well as DivX doctor II. When I run the AVIs through the doctor, an error message appears when it is finished, saying the audio may be truncated. The AVI has then been converted to a .mov, with one second of audio, and silence the rest of it. The video track format is provided as 3ivx D4 4.5.1, but no other data or encoding format is provided. I have been told that the video and audio work perfectly on their previous computer, a laptop running modern windows, so I highly doubt the audio is corrupt. So, what do I do? Am I missing a vital codec? Is there a better(free) avi player for Mac OS 9.2.2? Or will I just have to wait to get OS X 10.3 to download the divX player?
