Yes.
I do not have any issues with the podcasts that were originally posted using podpress. They seem to have converted just fine and show up correctly in the posts and feed. Only the episodes which were created using PowerPress are not showing up in the non-feedkey feed (but they show up if you append the feedkey). The 49 tags that show up were the previous 49 episodes all created under podpress, the 50th and newest is the issue.
