Is anything being done about what looks like a slight change in aspect ratio? I'm not saying it's just in the clip; it's in the original film. It occurs just after 3PO says, "The chances of ... blah-blah-blah", and it cuts to Chewie howling. It's at about 2:06 on the clip.

This happens a few times during Empire Strikes Back. The picture seems to stretch.

I apologize if this has been mentioned before, but I meant to mention this happening at another point, so I thought I'd bring it up here, as it affects this clip too.
