I downloaded a AVI video from googles website, clicked on the video but the video would not play. Quicktime opened the video along with a error message. The error message said that additional third party plug-ins are required to play the video that I was trying to watch. QTs website had a long list of links that lead to a bunch of 3rd party plug ins but there were too many to chose from, and I did not know which plug in to choose, Could someone please help me out ? Quick time is starting to annoy me, big time. First Quicktime is not compatible with WMV format now AVI is not compatible. Macs are awesome but they gotta find a way to make QT more extension friendly.
