Thanks for your attention to this "bug" to-date. I guess it's going to be one of those where I eventually get an 'ah ha' moment.
It's curious that it doesn't happen with a single podcast.
I'm guessing it's related to my previously reported issue with dbPoweramp:
/t/17085/1
I'll get around to deleting that program to see if it helps. When I find out I'll report back for future reference.
