 Replying to [ticket:7183 oerg866]:

 > FFMPEG will process concatenation of vob files with subtitles
 agonizingly slowly (less than real time speed on my i9-7900x with stream
 copy!)

 Looks much faster than real-time.

 In any case, the speed of this operation is not related to your cpu but
 your drive speed.
