Hi, I really want to change some of the theme songs on certain tv shows. Issues mostly, The quilty or just a horrible song. I want to be able to pull a song from youtube edit it. Then upload it to my server for a pacific show.
As long as your anime library uses default TheTVDB agent, this is possible.

If you have installed the HAMA scanner, you should ask its developer.
How do i get a hold of the developer?

Thank you I’ll private message him. 
Another way to get your own version of theme music is to add a file called THEME.MP3 to the shows folder. I do this on shows where I want the full version of the theme and not just the 30 second clip.
