Unable to delete podcasts from Ipod Classic.

I had a 160GB Ipod Classic stolen last month and bought a replacement online from someone in Denmark. Rather than being empty it's arrived with 3GB of podcasts on it, all in Danish, and I can't find a way to delete them from the ipod. The same question has been asked on here back in the day but in most cases there doesn't appear to have been a satisfactory conclusion.

It means I can't use it as a replacment for the lost ipod because I can't sync the just under 148GB of stuff from itunes onto it because of these rogue podcasts. The podcasts are on the ipod, not in itunes, and nothing I do seems to give me the option to delete them.

Any help very much welcome.
