Here is a full screen vs. widescreen comparison for Havoc.
The top cap is from SDTV (480i) and is about 1.33:1 aspect ratio.
The bottom cap is from HDTV (720p) and is about 1.85:1 aspect ratio.
The R1 DVD has about the same aspect ratio and framing as the HDTV but less res.
The SDTV appears to be open matte meaning more picture on the top and bottom. The sides are also slightly cropped. However, during one sequence in the Bijou Phillips sex scene, the SDTV reverts to pan & scan. I’m assuming this is so they don’t show any unintentional nudity. Fortunately, they didn’t touch the Anne Hathaway scenes.
