Investigate error in logs when OnlineVideos video is played

[GoogleCodeExporter]

When playing a video from OnlineVideos, MovingPictures logs this:

Error [VideoFormatExtension]: An error occured while validating 
'http://localhost/OnlineVideo.mp4' as a video file. System.ArgumentException: 
URI formats are not supported.
   at System.IO.Path.NormalizePath(String path, Boolean fullCheck, Int32 maxPathLength, Boolean expandShortPaths)
   at System.IO.Path.GetFullPathInternal(String path)
   at System.IO.FileInfo.Init(String fileName, Boolean checkHost)
   at System.IO.FileInfo..ctor(String fileName)
   at MediaPortal.Plugins.MovingPictures.LocalMediaManagement.VideoFormatExtensions.Validate(VideoFormat self, String path)

Since MovingPictures has nothing to do with OnlineVideos it seems strange to 
log this problem. This requires some investigation to find out why this is 
happening and avoid it.
