I discovered the pitch issue with another movie recently. One version played ~4 min. longer than the other one. First I thought of a missing scene but when I let them run together I noticed one version was gaining about half a minute in a quarter hour.

15 Minutes = 900 sec. ... x 0,04% = 36 sec.
so 4% makes the difference. Its actually the difference between NTSC (23,79 fps) and PAL (25 fps) if I am not mistaken.

The difference in speed is hardly noticable while watching the movie. In terms of soundtrack it must cause a real headache for poor ABC.
