Ahh I now understand what you wanted. You want a podcast feed, but you do not want the player and links in the pages.
Just a heads up, go to the PowerPress Channels menu, then edit the channel you created that you do not want shown on your site. Go to the "Media Appearance" settings tab, make sure it does not include a player and links in your pages.
The default podcast feature of PowerPress is technically a podcast channel as well. You can do the same thing by editing the default podcast channel and using the same setting under "Media Appearance". At that point though, the player and links will not appear anywhere for the main podcast, which may or may not be what most folks want.
