I have found a work around the bad blood between wordpress 2.6 and podpress 8.8 until podpress 8.9 comes out. It is a plugin: no revisions plugin. If you activate this plugin, you should be able to use wordpress 2.6 and podpress 8.8 together. Please note that you will get error messages when you try to edit or write new posts on some versions of IE. I had to use firefox which seems to work fine.
