The Toy Story change was made before the first DVD release. The original opening never made its way to digital home video, only laserdisc/vhs.
Did they reainmate the movie or restore it because it looks different from the Laserdisc
When they first released it on DVD, they did a fresh transfer from the original files. Most prints before that used the 35mm film print as seen in theaters (including the VHS that I have).
Oh so the DVD is from the Original Files nice
