Probably a dirty lens........try cleaning with a lens cleaning cd.

see that you do not use cheap quality media, this can also create problem.

AFAIK this is a clear problem of lens.And if am not wrong, cheaper dvd won't harm lens.

I have had this model for 10 months straight & so far not any huge issues as such.Mine initially had an issue with reading Dual Layer DVD's but that got fixed with the KLOM update.

The best thing to diagnose if it's the drive or your media then better take the DVD-RW disc to your friends place & check it out there.If it works fine then it's your Lite-On drive which might have issues with it's lens.Get it replaced under warranty.Make most of it while there is time else no idea when these driver screw up later on.

Mine has already shown signs of failing some DVD's when burned at 6X or 12X.But happens randomly.This started happening since I got that bloody starforce based game was installed on my rig.

thnks everybody , will try these methods......
