Yes, the back cover have the correct running time, but the actual master is speeded up for some reason. Also they reissued it since the LD was done before the Ellison settlement and Ellison threatened more with lawyers when he saw he wasn't included in it.

So you should notice the film is weird because of the speeded up pace (like it's in Pal or something), and you should notice the same soundmix, but with some weird stereo effects.

The full screen second LD by Image, the one with the gold disc logo on the front, is corrected and should feeature the correct film speed + untouched mono audio.
