Blu-ray Disk Merge DTS-HD MA Problem

[ghostp]

Hello everyone. I've a weird problem with merging a Blu-ray Disc. Here's what happened. I've a TV series on few BD's. I've extract some of my favourite episodes and want to merge them to one BD25.

Problem:
The episodes are with DTS-HD MA but after merging them DVDFab somehow downmixes the audio to AC3 5.1.

Question:
How can I merge the episodes (all are iso's) and keep the DTS-HD MA?

Can anyone help me please?

BD merge will conversion DTS-HD MA to ac3 5.1
It is right. We will improve it in future.

Hi Dora,

I started to think that nobody will answer me, so thank you for your answer

That is really a huge pity that DTS-HD MA is not passed thru
Could you tell an approx time when you are planing to improve this feature?

Thank you in advance
