I've recently started publishing my episodes in Mv4 to be able to use the added metadata, but the audio player doesn't seem to be responding to the Mv4. Thankfully, iTunes still plays the content correctly, but people can't play the audio on my site.
I do find this strange because I could swear it was working when I first installed, but overnight, it doesn't seem to work, only on these few Mv4 files.
Here are the links to the episodes if you want to see what I'm talking about.
Also, I tried this on both Chrome and Safari, and it doesn't work with either browser.
