I used the 8x dvd that came with my burner (the burner is memorex, and so is the dvd) and I was able to make a backup of a game perfectly (i.e. it loaded in swap magic no problems) but after that i tried using some 4x memorex dvds that i had bought before i got the burner, and so far 2 out of 2 games will not play. In swap magic, once i press "X" it acts like it is going to load, then it just continues showing the load screen (the moving stars), and the outer part blinks a few different colors. ALthough one of the games got past the load screen once, then hung up on its own loading screen. The burn process always shows "complete" and no errors, but no luck with playing the games. would it matter if some of the games are PAL, and my ps2 is ntsc (sp?) thanks in advance.
