I can confirm BDSup2Sub++'s behaviour as BizkitBoy told.
It even doesn't recognize the forced lines in it's own created XML-PNG (with forced flags).
Indeed the Java version works for this.
BTW, I always check the "Change frame rate" window and set both "FPS Source" - and "FPS T
arget" rates, even when no framerate change is needed.
