Harmy, I may have asked this before, but I can't remember- have you thought about adding the 1985 audio mix to v2.1? It would be cool to have all 5 audio mixes (1977 5.1, 1977 stereo, 1977 mono, 1985 stereo, 1993 stereo), for the sake of completeness and making comparisons. They're all unique mixes.
Happy new year, everybody!
