You either burnt too fast or your playstation is worn.

So, i've been successfully been copying my games-sound works and nothing wrong. But then i get around to copying my suikoden. And the sound skips. Now i originally thought it was my PsX, but it plays the sound on my other copies perfectly. Ive been using CDRWIN and it has never failed me...exept it has. It was burned the exact way as the others.. 1x. Could it be something like the Original had a smudge or something?
