Cannot play 3D bluray ISO properly

[pdh0710]

(Please excuse my English...)

I'd installed DVDFab Media Player promotion version from here
and activated the player using emailed key file.

My PC system is...
CPU = Intel Core i3-4150, Mainboard = ASUS H97i-Plus, RAM = 8GB,
GPU = Intel HD Graphics 4400, OS = Windows 7 Ultimate SP1 64bit.
All device drivers are installed properly.
My PC is connectied to Onkyo TX-NR515 receiver via HDMI for video
and coaxial cable for audio. TX-NR515 output is connected to LG 3D
UHD TV.
And I'v previously used other audio/video player progams, PowerDVD 14
for 3D bluray playing, Daum PotPlayer for other video playing, and
AIMP3 for audio playing.
I had no problem with this system and programs playing video(including
3D bluray) and audio files.

However, I have several problems for especially playing 3D bluray
ISO files. Two major problems are...

First of all, I cannot play the 3D bluray ISO files in 3D mode.
Mous right button menu -> Video -> 3D : disabled. I can't find
how to enable 3D mode.

Secondly, cannot use coaxial digital audio signal connection properly.
If I choose Settings -> Audio -> Output Mode:Optical/Coax,
I cannot enable "TrueHD/DTS-HD capable receiver"

How can I settle these problems?

As far as I know Fab Player can't play 3D Bluray ISO files. If it could I would use it :P
Currently only PowerDVD can.
