I've had my GDI-IR2000 for about eight weeks and at first things went swimmingly. I set up two "My Podcasts," Car Talk and Wait Wait Don't Tell Me from NPR, and successfully accessed podcasts for the next month or so. Then, suddenly, about three weeks ago, I stopped receiving new podcasts. Although the directory listed the new week's episode (2-13-2010, for instance), when I selected it for playback, it would play the same old episode from 1-23-2010. I went to NPR's website and verified that I had the correct RSS feed URL, so that's not the problem. What should my next step be?
