There are so many options for rewrapping Blu-Ray movies to MKV - clipwrap, MP4 Tools, MakeMKV etc - but I don't have the time to figure them all out in order to see which is best for me. I have about 30 Blu Ray movies that I'd like to convert to MKV in order to store them on my HD for easier access and viewing. I would prefer to leave the video untouched so that there is zero loss of picture quality. I'm sure that I could save some space by cutting out all the audio options except the regular highest quality stereo stream as I have never had a home surround sound system and no intention of getting one anytime soon. Paid or free doesn't matter to me. All I want is a program that will deliver excellent results easily and reliably. Lastly, I know that different movies have various audio streams for surround sound, Dolby etc. but I'm no expert in this area, so which audio stream should I choose for the highest quality stereo - AAC, AC3 etc? Thanks in advance for your help.
