I just got me a modded ps2 with a dms 4 se and everything has been working great but I sometimes get skipping or slow downs during movies in games. it sounds like a CD skipping. I tried burning the games at slower speeds and it fixed most of them but some of them still have the same problem. games that I rip to the harddrive run flawless no problems. just when i use the CD. could it be the lazer?
