Thanks for that piece of information! Fot me the resume option did not work at all (i.e. never - while the indicator would point to the right position, the audio would always start from the top). Thus, I uninstalled gPodder, deleted all related files in .cache, .config, and .local/share hoping to get a whole fresh new start. Now I'm trying again with new install. Fingers crossed!

Anyway, could you please explain what you meant by "not showing up..."?

Bonus question: Once you've listened to a podcast, how do you get rid of the file? On the N900 there was a menu dialogue to expire old downloads which I found very handy. Couldn't find anything similar with the Sailfish version, though.
