Terminator 3 Aspect Ratio

[denguy]

Can anyone tell me what the deal is here? I have the regular DVD full screen and the blu-ray widescreen version of T3 and wonder why the bottom 15% or so of the screen is cut off in the blu-ray disc. Compare the opening scene where Nick Stahl is sitting on the bridge holding a beer bottle. He drops it and in the regular DVD you see it careen off the bridge gutter and then fall into the water below. On the blu-ray disc, you see him drop it, then it bounces off the bridge gutter but you don't see it hit the gutter. This bottom part of the screen is cut off. The entire film suffers from this. The first scene where Christina Loken emerges from the storefront window you see her from the neck up on blu-ray. The regular DVD shows her from further away, just below her chest. It looks like Warner zoomed in and we're watching the movie from a closer vantage point than originally intended. What's the reason for this?
