Hmm, I don't see much from the verbose log output. If you want, you can send me the following information/files, which I need to see why the local files are not added:

* the output of ls -laR /media/mmc2/gpodder/
* all "index.xml" files in /media/mmc2/gpodder/downloads/*/
* the file /media/mmc2/gpodder/channels.opml

Thanks!
