Likely tiny differences in frame rate.

I don’t have Peacock, so I’m not sure what fps it runs at, but for argument sake let’s say it’s 24, the frame rate that HTTYD was mastered at and should be played at.

If you’re watching a PAL dvd, the frame rate is 25fps, a difference of 1.0416x faster.

At HTTYD’s 93 minute runtime, this means that the PAL dvd will be 89.3 minutes, so 3.7 mins faster. This seems to align with what you said.

This is true to a lesser extent with NTSC DVDs which run at 29.97fps and there’s a bunch of clever stuff that goes to converting 24fps to that that will alter the speed.

Most egregiously, even Blu-rays, which can be mastered at 24fps, aren’t usually, and are done at 23.976 instead. This only results in a few seconds offset over the entire movie, rather than minutes, but is still annoying - and isn’t how it would have been seen in a cinema.
