Hi Shawn
My apologies for the late reply, didn't see this 'til today. I used the Google Android app since that's where it was first rolled out. They said they were working on Chrome.
According to Google's specs, one of the things you need in the homepage is a <link type="application/rss+xml" rel="alternate" title="Your Podcast's Name" href="Your podcast's RSS url"/>and you're only supposed to have one of these. However, WordPress generates two links, one for the main feed, the other for the comments feed. So I don't know if that's preventing this from working or not.
For anyone following this thread, Google specs are here:

Thanks!
