 * I’ve migrated an old custom post type podcast to a new podcast channel. But now
   when I try to add a media url, it doesn’t like the “_” and the “-” characters
   that I use in URLs. How can I bypass this error without changing all my podcast
   episode URLs? 
   Here’s the error in particular after I click verify: “Media URL
   contains characters that may cause problems for some clients. For maximum compatibility,
   only use letters, numbers, dash – and underscore _ characters only.”
