Windows Library import results in items without details

Yes, it did work, but it's a bit more tedious than the single import, if it would work . Because you have to set the scraping order for tv shows (dvd or aired) again for every show needed, you lose the the ordering of recently added files and the links of movies to tvshows.
Yes, that's the tag for the tv show the movie should be associated with.
And back to the db stuff. I know SQL and relational databases, but not how xbmc associates things, because in the DB there were no old paths left, so I'm pretty sure the problem is with the lost association of thumbnails and the other info. But only the devs could clear this up, I guess.
