I turned to ahkpod since all my other clients broke and no alternative found.  Plus, ahkpod is easy to modify, since it is written in autohotkey.com language.  So, as I find bug, xml not working, I can fix it without extreme technical knowledge.

My review of other podcast clients that suck:  Itunes, deletes subscription if you manage the mp3s (as in transcoding them to smaller files);  juice and ippodder stopped working on latest java update;  Poppuppy is dotnet and unresponsivem and looses subscriptions and dl'd lists since stored in some registry or some windows directory that can be globally modified; podcastready is crap aimed at getting their content on your system.

This said, the 500 megabyte p.o.s. program called Itunes has a great store, which has the hottest free podcasts.  I haven't tried latest itunes (I am afraid of going beyond the version that was 40 megs for what it will screw up on my machine).   Also, all podcasters test their rss/xml with itunes.
