i can help to translate xbmc to spanish?? only xbmc, the manual is very complicated to me.
do strings.xml first.
we are in a feature freeze so no updates before 2.0, should give u the time to catch up. oh, please check that the strings render okay (i.e. are not too long).
i don't know how up to date the spanish translations are.
then submit it as a patch on sf.net.
