Hi, I want to convert DTS to AC3 because my TV doesnt support DTS.

I dont have a problem with the x264 video codec. I only have a problem with the audio codec.

I have a file Tag.2018.x264.720p-DRONES.mkv. There is only a single audio track on that file: DTS. I want to convert it to AC3, embed that audio track and remove the DTS track so that there is only one track on that file: AC3.

I have tried Handbrake but that takes too much time and my laptop overheats. I see there are many conversion software. What is the simplest one with minimal CPU usage?

Thanks in advance.
