Thanks admin, I actually resolved this issue a few days ago. The server was configured correctly. The problem had to do with uploading wmv files. VShare was not using ffmpeg to convert, and therefore no conversion was taking place. I change settings in the upload config file and now it's working (that is to say it is converting to FLV), however the quality of the wmv files I upload is not as good as when I upload them in AVI, so I'm using AVI from now on and going to recommend that users do the same.
