Back to the Future DVD Framing Errors

I just found out about this today. Apparently, the DVDs for Back to the Future II & III were improperly cropped when they were transferred to DVD. Owners of the original laser discs noticed some things they could see on the laser discs were off screen in the DVD version. Here is an example of the problem. I checked my discs, and sure enough, they are cropped. I guess I'll call the toll free number listed on that website to see if they are still replacing the DVDs. At the bottom of the page, they list several other DVDs where this has happened...I wonder how many DVDs this really happens to?
