@ SlyFox 1 , first I checked my computers clock (in the BIOS) it was correct with atomic time.
I had disabled all of my anti-virus & anti-malware software once before but I didn't have the Windows Firewall off.
This time I tried that as well. This didn't correct the problem .
The problem is with the DTS-HD MA audio track.
This is the only track without the "director's cut" audio.
If I uncheck the DTS-HD MA audio track it completes without an error.
Below are some .zip files with logs.
This one is with all anti-virus & anti-malware software disabled or off.
With the DTS-HD MA audio track only checked as well as the video clip.

The DTS-HD MA audio track is unchecked.
The English AC3 Multichannel is checked.
This is the one that works but has the "Director's cut" audio.

I have also used BD .iso named Sintel .
You can download a copy here :

It also works but only has AC3 audio.
That's all I have for now. I hope it helps.
