[See Bugtracker] Renaming Downloaded Filenames?

[LuckyLuciano]

So I download a playlist and all the video files and subtitles files are just simply named the video name. The problem is now the videos aren't in the playlist order so

I changed the filename extension in the plugin to *PLAYLIST_POSITION* - *3D* *360* *VIDEO_NAME*.*EXT*

which properly names all the files how I want it. However, I already downloaded the playlist and I can't find out how to change the video names of the files already downloaded. The new files added to linkgrabber follow the proper name but not the downloaded ones.

I tried the Packagizer and still doesn't change the downloaded files. Here is the screen I tried doing.
