Thanks to Drasi for this tip in a comment:
ITunes users who still have the duplicate; You will need to delete the duplicate episode, then hold down your shift key and click the arrow next to the “OutDPS!” podcast entry. That will load in all the feeds a fresh and you can redownload the updated one.
The double issue is caused by the fact that I forgot to update that “download directly here” link, and the enclosure got made from that instead of the standard streaming box. Anyways, I’ll be careful to double check both after this.
edit: Oh yeah, I forgot to mention. I’ll be in Dallas for boring RL meetings next week, and am planning on meeting up with a few wow friends in the area. If any readers live in the area, feel free to drop me a note and we’ll do coffee :)
