BD Ripper (3D Plus) MKV Passthrough Profile hanging every time

[colossus71]

Since 9.1.1.1 I've yet to get a mkv.passthrough rip to complete. Most die around the 66-75% range.

Here's a clean log of the last attempt...

Params:
* No CUDA or Lightning selected
* Ripping from structure created from DVDFab BDMV Copy
* MKV Passthrough
* Tried several HDD-located BDMV structures
* On 9.1.1.5, same results
* 8.2.2.9 works fine

Summary of error in log:

System Specs:
* Win 8.1 Pro
* 64-bit
* Dell Inspiron (Intel Core 2 Quad Q8200 / 2.33 GHz)

UPDATE:

Tried using the standard MKV profile to convert down to smaller size. Same results...

Tried the following two movies full structure rips (from DVDFab Copy):
Underworld Rise of the Lycans
Underworld Awakening

MP4 works fine

UPDATE 2:

So it appears that there's something unique about the two Underworld titles that hangs the mkv profile at around 78%. Both rip to that point and then DVDFab hangs.

I tried another unrelated title, same BDMV structure type ripped with DVDFab Copy, and it ripped using the MKV profile just fine.

As I mentioned before, v8 rips these two fine, as does an unrelated product. I'd be glad to furnish any information to help get to the bottom of this.
