When I first saw that stretch, I thought I found some weird artifact from the Blu-ray--but I checked the Laserdisc and it was there too. I think part of the problem is that when the image is all low-res, dirty, and shaky, a little stretching every now and then doesn't stand out so much. Now it does.
As for the compactor scene, I felt that way too and even PM'd Harmy about it, but if it's that way on the Tech IB reference, well I guess that's that.
