The DTS and DD tracks are the same. Missing frames were filled with black.
I guess my first step, for my attempt to run some automated cleanup (as I did with TN1’s releases) is to try to find these padding frames so I can remove them =p, since GOUT-compatibility doesn’t matter to me. But I guess my initial calculations were wrong, because I figured I’d see a cigarette burn and some padding around 22 min. in, and I didn’t spot either - then again, it takes forever to seek around a video like this (just the nature of the material).
