I recently had someone from sitepoint create a script for me that converts rss files to podcast mp3s. If you think you can complete this project I'll show you the script in action in the PMB.
What I'm needing for you to do is create a CUSTOM flash media player that takes an rss file and has the posts listed and when each is clicked, the mp3 (or any other format you can convert it to) is played.
It's somewhat hard to explain with words, but something similar to the one on: [url removed, login to view] (click the down arrow on that flash player and you will see all the posts drop down).
I'm somewhat new to the whole podcast thing so if there's some other format other than .mp3 and you can convert it to that also (for the user to download) along with the flash player, that would be great!
Let me know via the PMB of any other information you might need.
