@ KnightKinetik.
Thanks a lot for the quick reply. I now consistently can do your advised f,hcf (holding forward at the end) then C, but I just input C once and hold it (leniency seems even better in HD mode, dont know why).
It works, but comes out only at 1st hit of the enemy, otherwise just dp comes out.
However, when switching sides in the combo (enemy afloat in the air), although I do the correct & mirrored input either nothing comes out or just a regular dragon punch. Is there a specific timing or input window to it ? Or does hold C negate the follow up input, maybe?
Eventually someone indeed has/could make a input video or something ? it really drives me nuts (checked all over youtube, this specific combo has no inputs shown, even if Bala uses Andy in a few videos).
(holding the second C)
