Also ffmpeg with the -ss and -t or -to options, although it's less accurate (according to the integrated help, -t only accepts a duration in seconds, for -ss and -to it's unclear – see below). For instance this should cut a 5min chunk of movie.mkv from 10:00 to 15:00 :
ffmpeg -i "movie.mkv" -ss 600 -t 300 -c copy "movie - cut.mkv"
-t duration record or transcode "duration" seconds of audio/video -to time_stop record or transcode stop time -fs limit_size set the limit file size in bytes -ss time_off set the start time offset
