Below is a frame from the DVD movie. Marty's 70mm frame does not exist in the 35mm DVD movie so I couldn't get a exact match. But, as you can see, the DVD frame cuts picture info from both sides and the bottom.
Below is the actual 70mm frame from Marty Hart's Widescreen Museum web site - http://www.widescreemmuseum.com
Below is a frame from the extras section on the DVD. Compared to the 70mm frame only the right side is cut.
