ME1 PS3 version, decryption minigames way too fast (possibly bugged)

I had trouble at first, but figured it out.  If you hit each button prompt and hold it for just a split second longer, then it registers.  Do that for all 3 button presses and it should work. Took me about 10 tries to figure it out, but after I realized what to do, got it on first try.

PS3 digital download, TV in game mode.

Example: Triangle comes up, press triangle then hold it for a split second, Square comes up, press square, then hold it for a split second, X comes up, press X, then hold it for a split second.
