Okay. The other plugins are not involved and the rewrite rules are looking to me.
I'm still not able to reproduce the problem.
Would you do a further test?
If the problem is not limited to podPress then it will probably happen when you add a further Feed with a different plugin.
The following code snippet is a simple plugin which adds a RSS Feed to a blog. This Feed with the slug name "testfeed" will have the same content as the main entries RSS Feed.

Create a new file with a text editor and name it e.g. testfeed.php.
Open the file with the text editor and copy and paste that code into the file.
Upload this file to your blog and store it for instance in the folder /wp-content/plugins/testfeed/.
Afterwards head to the plugins page of your blog and activate that plugin ("A Test Feed").
This will create the Feed /?feed=testfeed (and /feed/testfeed).
Choose a non-default Permalink scheme and save the Permalink settings.
Does /?feed=testfeed work?
Does /feed/testfeed work?
If /?feed=testfeed is not working while the non-default Permalink scheme is active (and /feed/testfeed is working), deactivate a part of the this plugin by inserting comment characters in one line of the code. You may use the plugin editor of the blog for this action.
Modify the code like this:
old:
function testfeed_do_feed($withcomments) {
testfeed_modify_certain_feedelements();
do_feed_rss2($withcomments);
}
new:
function testfeed_do_feed($withcomments) {
//testfeed_modify_certain_feedelements();
do_feed_rss2($withcomments);
}
Or you modify the file with the text editor on your computer and upload the file again.
If this is also not working then you should try this code:

(This is comparable to the way the podPress versions before version 8.8.9 have added the Feeds.)
If the /?feed=testfeed URL does not work while /feed/testfeed works (while a non-default Permalink scheme is active) then it is probably a problem which is not limited to the podPress plugin.
Please, control also the /?feed=rss2 and the /?feed=atom Feed while the non-default Permalink scheme is active.
Is the RSS and the ATOM Feed working?
If the ATOM Feed or the /?feed=testfeed Feed is not working then turn off the podPress plugin temporarily and test the ATOM Feed and /?feed=testfeed again (while the non-default Permalink scheme is active).
This may not bring the solution but it will definitely help to narrow down the number of possible sources of the problem.
