Laser Issues

[SupaKEn]

Hello, I've been burning backups at 1x read/write speed onto Ritek DVD-R's, and everything has been working until recently. Many of my burnt games run very choppy, and cannot even play BG music without it skipping.
I read something on here about adjusting my laser(i've already cleaned it) Can anyone point me to where that guide is?

thanks
