Like I say in Videohelp forum please put a MediaInfo of the file.

NicAudio work with 2.0 DTS files but not with LtRt DTS.

If isn't the problem maybe your file is corrupt.

But this is a .mkv with a track 2: DTS 5.1

How have extract you the "T2_Audio - 2.0 channels.dts"?

I need the Avisynth script (full log, Right click -> Save -> Log, and put here the .log file) to analyze the problem.

Try replacing C:\Users\ZIVKO\Desktop\MeGUI_2028_x86\tools\avisynth_plugin\NicAudio.dll" with the attached one.

If don't work I think the dts is corrupt, try DelayCut to fix.

Wow, it worked! I can encode now. Thanks a lot man, really! But to be honest I'm more interested in what the problem was...?
Is this nicaudio an older/newer version or... ?

Is a new version 2.0.5 with only this upgrade.

The DTS specs can use different channels arrangements:
Code:
Table 5.4: Audio channel arrangement
AMODE    CHS Arrangement
0b000000  1  A
0b000001  2  A + B (dual mono) 
0b000010  2  L + R (stereo)
0b000011  2  (L+R) + (L-R) (sum-difference) 
0b000100  2  LT +RT (left and right total) 
0b000101  3  C + L + R 
0b000110  3  L + R+ S 
0b000111  4  C + L + R+ S 
0b001000  4  L + R+ SL+SR 
0b001001  5  C + L + R+ SL+SR 
0b001010  6  CL + CR + L + R + SL + SR 
0b001011  6  C + L + R+ LR + RR + OV 
0b001100  6  CF+ CR+LF+ RF+LR + RR 
0b001101  7  CL + C + CR + L + R + SL + SR 
0b001110  8  CL + CR + L + R + SL1 + SL2+ SR1 + SR2 
0b001111  8  CL + C+ CR + L + R + SL + S+ SR
The libdts decoder reject the mode:
0b000100 LT +RT (left and right total)
like invalid, I only change the code to accept this mode like:
0b000010 L + R (stereo)
