"Pages" not support in feed

I’ve associated a media file through the PodPress meta box on one of our pages in WordPress. However, the feed doesn’t seem to pull in “pages”…it remains broken (as if no podcast episodes exist)

When I add a media file to a blog post, the feed works. In the “Post Type Filter” option in the PodPress settings for this feed, it displays Posts, and all my custom post types, but does not show “Pages”.

Are pages not supported to generate a feed?

Thanks in advance for any help on this.
