Wrapping DTS files to MKA often creates unusable MKA files.
I've had DTS audio-only - typically 6 channel files - result in unusable MKA file outputs. Example - MediaInfo:
The above file is about 50 MB's - results in a 13kB MKA output. No errors in the Job Output or Queue tabs. New here - Let me know if you want a source file example.
