IIS 7和php大文件上传问题

I've been trying to upload some avi files by using several methods. First I've tried using ADOBE's ADDT "UPLOAD FILE" to upload *.avi files, everything was ok, until I've tried to upload a 131.5M video. When the size of the video is less than 40M, there's no problem, but when the video is bigger is where the problem starts. So tried different methods, jquery plugins, etc, with the same result. The server in which the movies should upload is running under IIS7. Making some search over the internet, I've found that the php.ini should be changed, so I have the following related values changed: max_file_uploads:20 max_input_time:240 memory_limit:256M post_max_size:256M upload_max_filesize:256MI've been trying to upload some avi files by us
