Hey guys, not sure whats going on. I had this avi video playing fine on my old powerbook. moved everything over to my new macbook and other avi files are fine, but this one crackles during the louder parts of the video. no mater what the volume (both computer and video properties) are set to. I have all kinds of codecs (even tried selectively removing some to see if it would help) and A52 audio component installed, but still to no avail... and ideas?
