This is a pre-release of the new Freevo skin based on XBMC Confluence skin. All instructions are in the README file in the archive. Feedback, bugs and problems should be reported to the freevo_devel mailing list.
As I cannot add this file to the tracker (I suspect the file is too big @25MB) I made it available for download from my server:
