Thank you very much for responding, and please pardon my ignorance however when I go to the output module in the render queue, there is no option for vc-1 or video for windows. I am running ae cs3 on an intel macbook pro (version 10.5.6). I have created a xmas video for neighbors that have a pc that does not have quicktime installed (quicktime interferes with their business, disallowing them to view certain tiff files online of recorded plats???). I thought they would be able to view it with Windows Media Player, however when the dvd is inserted into their computer, it does not even recognize that a disk is in the f drive. ????
