I think the cloud city vane shot is a matter of perspective (windows) of where u are viewing it, it looks fine on the DVD to me. On a side note, some people say this entire vane is too small to house the carbonite freezing chamber at the top but if you get the DK Star Wars COMPLETE LOCATIONS book, you will see it fits nicely. Now if someone could just post those stills of the gray tape that turns into black char marks in the next shot on the vane thing vader cuts in half before he cuts off Luke's hand.
