M4V audio problem, stereo plays fine, 5.1 AC-3 choppy
#1
Sad 
I have a few movies in M4V. In Stereo they work and playback fine, when I switch to 5.1 the audio and video get choppy.

My system:

Windows 7 64 bit, XBMC 10.1
ASRock AMD Zacate E-350
4GB of RAM

I have no codec packs installed.

Here's a read out of a few of the movies in question:

I have DXVA enabled, full screen window instead of true full screen, video is out via HDMI and sound is out via toslink optical.
