I came across with this youtube video reviewing a tiny little wonder called Griffith.
What is Griffith?
Griffith is a cross-platform application and is known to run on GNU Linux, Microsoft Windows and MacOS X systems. Probably, it will run on other POSIX compatible operating systems where a gtk+ environment is available, including FreeBSD, OpenBSD and Solaris.
It is a media collection manager application. Adding items to the collection is as quick and easy as typing the film title and selecting a supported source. Griffith will then try to fetch all the related information from the Web.
I havent ran Griffith on linux but in windows runs smoothly, but be shure to be carefull to backup your DB, otherwise you’ll need to add all items to your collection, from scratch.
If you know about some other good alternatives to Griffith, PLEASE let me know! (:
