You mean the codec-based one? That is a explicitly user-selectable
option.
The reason it exists is exactly the instability. It seems that Carl
unfortunately had a point that this old method seems to be the most
reliable still.

Kind of, but I can't blame them for not testing things that are
not easily testable.
I could blame people for not writing tests, but on the other
hand I never finished my attempts either.
So I'll only blame people for not actually showing interest in
proper testing, but that seems to be standard operating mode
for both MPlayer and VLC, unfortunately.
