For each Title you can click the plus sign to view detailed information such as video codec, size, audio codec, language, subtitles and so on. You can select which titles you want to save and what tracks to keep in each title. Uncheck the audios and subtitles you don’t like, and the others will be reserved.

By now you have ripped Blu-ray movie into MKV file and passed original video and audio quality through into a file playable on a typical hard disk media player.

2. If you would love to change TrueHD, DTS-MA 7.1 audio to AC3, AAC or DTS 5.1 sound, click “Edit stream” button to set audio codec and channels.
