Using mmc2 seems like a big no-no to me. I actually have gpodder's config files on mmc2 and keep all my podcasts on mmc1 (where I have MUCH more space and can remove the card more easily).

Shouldn't gpodder be using a ~/.gpodder for its configuration (just like on the desktop)? That way it can have all the database and podcasts identified as existing on EITHER card without requiring mmc2 to be touched at all with the added benefit of getting included in backups when you use the n8x0's backup tools?
