通过php上传视频文件到IIS 7失败

I'm trying to get my website to upload video's and pictures. As I have made more websites that upload pictures there is no problem on that front, but when i try to upload a video for some reason it can't be found in the $_FILES array that contains an uploaded image.

I have already googled and found stuff about the php.ini file and IIS 7 containing max sizes for uploads. these are all set to 1024M:

In php.ini:

max_execution_time = 1000
max_input_time = 1000
memory_limit = 256M
upload_max_filesize = 1024M
post_max_size = 1024M

In IIS 7:

maxAllowedContentLength = 1073741824
maxRequestLength = 1073741824

After some testing it appears that really small video files do work (192KB) but somewhat bigger doesnt show anyting in the $_FILES array (11MB) but really big files (80MB) gives an error: The request filtering module is configured to deny a request that exceeds the request content length.. The problem is that i have set the maxAllowedContentLength to 1GB. So that shouldn't happen?! An image of this is down below:

Any help or advice is greatly appriciated!
