Well, it all seemed to be going too smoothly. You will notice in your itunes feeds that your downloads have doubled. I think this was caused by the feed change. iTunes wasn't quite smart enough to check for downloaded shows after the feed switched over and all the old shows re-downloaded. If it is bothering you to bits, you can do something about it.
If you look at two file names, the one with the longer description, usually the second one, is coming from the new feed. You can delete the first one. I'm going to be recording a new episode tonight that will ONLY be uploaded to the new feed, so if duplicate files come in for episode 33, I'll know there is a real problem. Thanks for your patience and sorry for any inconvenience.
