I'm back to work with BATB; sync'ing the BD and the final video, I noted that sometimes the BD has more image than laserdisc on the sides, while other times the BD has the image cropped top and bottom... see for example the next two frames, that are one after the other:

according to IMDB:

Aspect Ratio

1.66 : 1 (negative ratio)
1.50 : 1 (IMAX version)
1.85 : 1 (intended ratio)

so, it's odd that the BD uses both 1.85:1 and cropped 1.66:1, while the laserdisc uses only the 1.66:1 not cropped... maybe an expert could write he something more about this.
