Hi, I have after effects cs3, and i have been having trouble with rendering videos. when i open the render queue and click the "format options" button for a wmv or mpg or a few other formats, after effects freezes. sometimes even when i just select certain formats, it freezes without clicking on the format options button. I would really appreciate any help i can get. By the way, the quicktime format works perfectly when you open it and so does the format options. but i prefer to use wmv so that doesnt help me at all. thanks again.
