An HttpException is thrown when a MovieUrl contains a query string


If you set the MovieUrl property to a value that includes a query string (~/movies/somemovie.swf?data=data.xml), the control will throw an HttpException when attempting to convert the rooted path to an application relative path. This exception is thrown by the VirtualPathUtility in the .NET Framework.
The solution is to seperate the path and the query, then make the path relative and append the query portion of the URL to the relative path. This has been lightly tested and will be released in a build within the next few days.
