Update: Had another listen to the audio track. I think it is actually a 
bizarre interlace of the Spanish and Original Lamnguage tracks. Could it 
be that because it is a FF DVB-S card I am trying to open two audio 
streams at the same time ( with the original code opening the Spanish, 
and the added open statement opening the Original Language ? )
