I ripped a HD BR movie that spans 2 discs. I ripped them both into separate mkv files at high quality settings, one approx. 12 GB, the other 11 GB. Now I would like to join them together into one file so that I can load them onto a USB drive and watch the movie un-interrupted on my TV (which accepts USB drives to play movies, music, etc.).
Is there a utility (preferably free) where I can easily join one mkv file to the end of the other mkv file and get one file with the same quality as they were originally ripped? If not MKV, what about mp4 (I can re-rip the discs to mp4)?
