I'm implementing a site/blog where I'm going to share several podcasts about different topics (for the example, lets say that one topic is "roleplay sessions" and the other one are discussions and tips about "roleplay games" like dungeons and dragons)
In my mind I would be 2 different series (ex: "Down of times" for the sessions and "roleplay tip" for the other topic)
Now, the current language I presume is used on itunes to inform the user about the language of the podcast/episode (?), but since I have only 1 podcast (and no series) they are all mixed up. However, the "roleplay sessions" episodes are sponen in French and the "roleplay tip" episodes are spoken in English.
The idea was to show that information on the player (or near the player using the templates) so that people are aware and informed about what they can expect to hear.
From another podcast plugin: "Podcast series are not just a convenient way to group your episodes – they also allow you to run multiple podcast shows from the same site with series-specific RSS feeds that you can make entirely unique."

Makes sense ?
