I have a HTC Arrive, and had some podcasts loaded on it. The podcasts were loaded as regular mp3s, as they weren't available on Zune, and I had just downloaded them off the internet. They're listed together in a playlist. After loading them, my hard drive crashed and I had to reinstall Windows and Zune on a new hard drive. I also had to list my phone as belonging to this new computer. Now, however, I can't delete any of the podcasts (and only the podcasts, I was able to delete the rest of the music) off my phone. Is there a way to do this without completely resetting my phone to factory default?
