Podcast works in iTunes on Computers ONLY

I have a podcast using Blubrry on my s2member website. I am protecting the podcast using Remote Auth / Podcating Remote Header Authorization.

The files are hosted in my s2member-files folder. the url i am entering into the Blubrry interface as a Mob Re-write is as follows:

http://erichschiffmann.com/wp-content/plugins/s2member-files/s2member-file-remote/s2member-file-inline/s2member-skip-confirmation-n/s2member-file-storage-local/access-s2member-level0/2012/11/2012-11-15a_be-relaxed-Talk-vc.mp3

the subscribe URL is http://erichschiffmann.com/podcast

The podcast works perfectly in iTunes and on Computers BUT won’t work (authorization / ask for password etc) on iPad, Android players including the Google Listen App. etc. In Google Listen It says it cannot find File although it sees podcast and title of the 2 podcasts that are published once i subscribe. I the iPad it just can’t find the podcast to subscribe. How do i get the Android players to ask for password? How do i get the podcast to work within iTunes on iPad & iPhone.

Any help would be appreciated.

I just noticed in the feed URL http://erichschiffmann.com/podcast page the s2member-files URL is revealed completely.

does this present a security issue if people can easily see full mob rewrite address and code and is this maskable if it is a security issue?

i have also posted this question at blubrry if you want to check out the progress on solution.
