I have a lot of MKV files and I've been trying to figure out how to add on DTS or TrueHD or any sort of audio to any of them that don't have true surround sound. Is there a website that I can download these Audio files from and may be parse them on to the MKV files using something like MKV tool knix? How about fixing existing MKV files with audio issues? i.e. I have a MKV file for Total Recall and the TrueHD audio on the files cuts out every 10 mins for about 3 secs and it's pretty annoying. I would love to be able to fix something like that.
