If it is available as a podcast, you may have better luck using FeederReader in combination with TCPMP / BetaPlayer / CoreCodec. If you do find a podcast for what you are looking for and you need help on playing it, let me know on the FeederReader Forums. There are some specific codecs you may need to install depending on the exact media file.
