go to Tools -> Settings -> Demuxing and disable DGDecodeNV
This works, Selur!
Excuse me for not knowing the program: there aren't many guides available for understanding it.
By the way, if this can help others, in "demuxing" there are two entries, perhaps related to the problem:
- DGIndexNV - Demux audio and index
- DGIndexNV - Index audio demuxing MKV Without
I unchecked both.
If I'm wrong, let me know, please.
Thank you very much for your reply,
