I guess that it comes down to the format. You can convert the files to mp3 using iTunes and drag them directly to the flash drive.
To explain more - it is a web based podcast - when I play on computer it plays on a Quicktime webpage - dont know how to /if I can save it to iTunes or in any mp3 format
To download the audio instead of have it play in Safari... just hold down the Option key when you click on the link. That should save it to disk and you can just copy it to your usb drive from there.
