I've now converted another movie on Leap 15.2 and 15.3 each. The full
output from mediainfo is attached to this e-mail (hope it'll get through

The most interesting item to me is this:

All these elements exist only in the file produced on 15.2. Will compare
the presets between both worlds, but I presume some elements are missing
in the 15.3 version.
