Here is my feed in FeedVaildator and it shows the audio (with the blubrry media urls)
http://feedvalidator.org/check.cgi?url=https%3A%2F%2Fburtnetwork.com%2Fcategory%2Fgoodcoachbadcoach%2Ffeed%2FI also see that there are no episodes when I check Firefox as well...which is strange...
I am not doing anything different than what I have normally been doing. Setup a category, setup category podcasting, add audio to a post and verify, add post to category, and it always shows up in the feed after that and in iTunes.
BTW, thanks for your help on this!
EDIT: Also, some of those errors (like the one about the image not being a full url) seem invalid on FeedValidator.org...unless you care to shed some light, but the feed images always work.
ADITIONAL EDIT: Feeds show up without audio, but as soon as I put the audio on the post it errors out.
