I've been in Dublin for vacation this week and I bought the complete season 1 because it says that has spanish subtitles, but it doesn't. This are the confirmed audio and subtitles: Audio: English Subtitles: Danish, Swedish, Finish, Norwegian, Hebrew, Portuguese, Icelandic and, of course, English for the hearing impaired.
The box cover for this DVD says French Italian Portugese and Spanish but the dvds inside don't have these subtitles. I am very angry because this is clearly misleading. Sorry if I misinformed anyone. I have paid out for this DVD and there aren't any French subtitles.
The dvds I got ...Vol 1 has Danish Flemish Norwegian ,Swedish and English. Vol2 Danish Finnish Hebrew ,Icelandic ,Nowegian ,Portugese Swedish and English. but the box cover says French Spanish Portugese and Italian. Ps I got mine from Play and they are sending me a second set. I will let you know what the subtitles are on that.
