Lee,
There actually IS a direct URL you could try. The MAPP show audio files are loaded on Libsyn, just like the public shows, but their names are “encrypted” so they can’t be found. If you right-click on the “Listen to the Show” link, you can copy the URL. For example, MAPP Show #31’s URL is http://traffic.libsyn.com/podcacher/PodCacherm6v8k9.mp3
Try that with Pod Wrangler and let us know how that works. It might be a solution that others could use as well.
