#2439: Add support for ivtv-generated bilingual dual audio MPEG
-----------------------+----------------------------------------------------
 Reporter:  anonymous  |       Owner:  ijr    
     Type:  patch      |      Status:  new    
 Priority:  minor      |   Milestone:  unknown
Component:  mythtv     |     Version:  head   
 Severity:  medium     |  
-----------------------+----------------------------------------------------
 The Hauppauge PVR250+ cards can record bilingual broadcasts and flag them
 properly as containing a DUAL audio stream (= a stereo stream with left
 for one language and right for another language)

 This patch adds support for this feature to mythtv:
 1. switch the flag on in the recording profile
 2. play MPEG files with dual streams properly, as if they contained two
 independent streams

 This only works with PRV250/350 cards when using the X output (not the PVR
 350 output)

 background, history and usage information:

 The patch attached is meant both for the 0.20 branch and the head.
