2012 2009 Audio Track 720p BluRay x264-x0r

As you must have realised by now if you have downloaded the 2012 2009 720p BluRay x264-x0r torrent, the original audio track is seriously faulty. x0r being one of the best uploaders, I don't understand why he didn't correct that mistake. No worries : here is the perfect audio track (AC3 448kbs) to mux with mkvmerge. I did it myself and it works like a charm. Just make sure to keep the commentary track when you do it.
Enjoy !
