Ok, I created an audio CUE file, I also updated chapters and subs in this updated complete package: htda2013-04-12.SubsAndChapters.zip
So you can add chapters, subs, if you want... But your 1080p file produced MANY errors in remuxing/playing/subtitling (when creating subs, refuse to play, as in my usual ZoomPlayer, direct remuxing produced warning message and unsync).
You may receive many play complains, I fixed it with the commercial TMPGenc Mpeg Smart Renderer 4, this tool is famous to edit videos without recoding them, ( well, it will recode minimum, the cut parts for example). In your case I watched it work, it recoded many small video parts, but also kept a lot of untouched video parts, it gave me a playable version, who allowed me to work. So you can say it smart-fixed your video file.

Back to what's new: I used chapter file on your audio, and tweaked it to produce a CUE file. This will help you extract and cut a perfect M4A version of the live show, instead of the actual MP3 version. Only one lossy compression: the one did by youtube. The audio in your file is not damaged and workable.
Quick instructions :
-Use freeware YAMB for example to extract the AAC/M4A file
-Download and launch freeware mp3directcut not forgetting to add libFAAD2 dll for Win32 so it will play AAC files.
-Mp3DirectCut is famous for being able to edit without recoding MP3 files but also MP2 and M4A via additional free dll
-Load the AAC file
-Special/Load CUE sheet over current audio file
-File/Save split
