I'm not sure if anyone has encountered this particular issue before, but when I reached the end of Fate/Stay Night: Realta Nua's prologue, and the opening movie starts to play, it became quite erratic, it would freeze in certain places and loop the image/sound continuously before advancing about 5 seconds, and then repeating the problem. This isn't game-breaking, and I have yet to experience any other issues, but it is quite immersive breaking (in a way.) Any insight on this would be appreciated.
