I contacted a seller of the laser disc on eBay and he checked the running time. Even though the cover says 165 minutes the actual running time is:
Side A = 56.47
Side B = 54.06
Side C = 47.36
158:29
Compared to the DVD, the broadcast is cropped on top, left and bottom to get 2.35. Your getting about 2.1 of the 2.76 image width. So, missing about 25%.
