any which way you can / every which way but loose has new added foley effects . while they sound good, nothing ever sounded like that in the late 70’s.
the jerk - new foley effects and a pointless 5.1 mix . The original mix is on the old 4:3 DVD.
one flew over the cuckoo’s nest - another point less 5.1 mix w/ added foley. The old flipper disc might have the original mono.
the godfather series has the original mono but heavily compressed 2 channel 192kps . If it was at 1.0 192kps I don’t think the compression would be as bad.
