I'm working on a media metadata import utility for XBMC. What I have is a XBMC windows box with some of my media backups on it. The plan is to setup the media as share(s) and then use the export function within XBMC to puke the database into a single XML file that will be used to tag everything in LinuxMCE with. Once the metadata is added to the LinuxMCE database, UpdateMedia will create .id3 tags for all of the files.
I have a script that automates the process, just working out the bugs on it. What I want to do next is add it to the web admin. From a user's perspective, it should be as easy as selecting the XBMC videodb.xml file in our web admin, and then drink beer until it finishes. If there is anyone out there who has media in XBMC they want to import into LinuxMCE already tagged, please let me know as I'll be looking for someone to help me test it before I get it folded in to the system.
Hopefully this can help encourage some XBMC users that have been sitting on the LinuxMCE fence to jump over
