The php file upload seems to work well for small file, but when upload a large file (video), I always get a Silverlight exception

 

Your document says the default max file size is 2G so I commented out the setting, but that does not help.  I'm just using your form-simple-upload.php page:

 

 

 <div class="demo">
        <h2>Upload</h2>
        <p> Browse to and upload your video.</ul>
  <?php
   $uploader=new PhpUploader();
   
   $uploader->MultipleFilesUpload=false;
   $uploader->InsertText="Upload File (Max 2G)";
   
   //$uploader->MaxSizeKB=1024000; 
   $uploader->AllowedFileExtensions="avi,mpg,mp4,wmv";
   
   //Where'd the files go?
   $uploader->SaveDirectory="savefiles";
   
   $uploader->Render();
  ?>
