Complete, uncut console output missing, I don't remember 
a question where mediainfo output was useful.

How do you know that your input file contains surround 
information? Is it because you have a dolby certified 
receiver that allows you to play two-channel audio with 
surround effects? In this case, do not reencode audio: 
FFmpeg has a Dolby PLII encoder (resampler) but no 
decoder, just convince xbmc to not mess with audio and 
allow your receiver to do what is necessary.
(Analog input may be required iirc.)
