Hello nostra,
currently it looks like the "Display aspect ratio" from mediainfo.dll is used to determine the value
for the the respective database entry in PVD.
May I suggest to use the "Original display aspect ratio" (if available!) from mediainfo.dll in future
versions of PVD instead, since AFAIK this value reflects the DAR of the video container format
which is respected (and used) by almost all modern players like MPC-HC, VLC, SmPlayer etc. ?
TIA Chris
