Oh... You're right !
I've kept since a long time both this one and
MPEG2DecPlus in my project directories, but i've just realised that i've never opened the project of
DGIndex_mod...
I thought i had, but i was mistaken. I only opened the
MPEG2DecPlus (a little while ago already) project with visual studio (2017 i think at the time) just to check if i was able to build it. According my memories, building DGIndex with VS2017 failed, but the DLL succed.
I thought i also made the same experiment with
DGIndex_mod, but i was mistaken.
At least, there is no question about which could be "better"...
The only thing i still didn't check is if
MPEG2DecPlus implement all the features of original, especialy the only mode i'm using
IEEE-1180 Reference... Well, in the very very very ultra rare occasions i'm still working using DVDs as source...
Edit
Looking at the code of
MPEG2DecPlus it seems that
IEEE-1180 Reference is implemented.
