I am trying to back up a Ps2 game that I own.Every time I copy it it plays all the intro stuff but when I try to play the game it just stops.I have tried my only 3 games & they all do it...Is this a media problem a software problem or I am just doing it wrong...I am using Nero Burning Rom...The media is Memorex DVD-R..I have a pioneer A04 DVD-R Burner.....What media type or software should I be using...Also I use the swap disc method...No chip installed...
