This disc suffers from an audio defect for over 7 1/2 minutes on analog channel 2/R, which features the commentary track by actor Don Taylor. On my copy, there is a drastic drop in volume level on side one beginning at 38:47. This makes it very difficult to hear Taylor's commentary at times. The volume suddenly returns to the previous normal level at 46:20. The other audio channels seem to be unaffected by this problem.
