Oldfan, Matt, thanks for the feedbacks!
Both commentaries are taken from DVD, untouched; I was sure that the first one was the same of the laserdisc, but if it's true that something was cut for the DVD version, then I could think about to capture the laserdisc one next time...
For BD playback issues, I opened a dedicated thread, to gather all comments and try to find out a solution; please post your BD feedback there, thanks!
