I am also having a similar issue, none of my media players that are able to play podcasts, will open or find any episodes from the subsonic generated podcast which is supposed to list saved playlists.
I found this warning in the subsonic log and I am wondering if it is related to the issue:
WARN PodcastService Failed to get/parse RSS file for Podcast channel
http://myhostname[<-edited]/subsonic/podcast
Also this is the error itunes gives when i update the podcast from itunes:
"There are no playable episodes for 'Subsonic Podcast'.
the url might point to text-only episodes, or contain file types that iTunes cannot play."
my podcast directory is located inside the music directory and I created the folder with full permissions.
The playlist folder is outside of the music directory but also has full permissions. I checked it and the playlists are located inside.
I also loaded the podcast rss into firefox as a live bookmark to make sure it was listing the playlist names, which it was. Im not sure what else to do to make subsonic's generated podcast work, because I really like the idea of that feature.
Do you guys have any ideas?
