How it works now
Originally the Scripts Plugin checked for a file extension, if it was WMV then the video was set to Windows Media, everything else would be Flash. This proved flawed as server side parameters break this set up. As an example http://www.url.com/video.wmv?hashcode=ff7fa02b would be interpreted as a Flash video when it is a WMV. So instead of checking file extensions I changed it to simply check for the existence of .wmv and if it exists then it will set it as Windows Media. Still flawed however when you consider a url like this: http://www.url.com/video.wmv.flv the plugin assumes it is a WMV file which is incorrect.
Version 0.7.0.0 will be released a short time after Thanksgiving.
