My problem is that my buffer keeps droping to zero every few seconds. I am running windows xp with 512mb ram. I have a plextor premium and am using the latest version of nero. I have searched the internet and found nothing. I know that formating my system will fix this problem for a while. I have tried defragmenting, reinstalling the cd rom, reinstalling atapi, upgrading nero, rebooting, everything. Please can someone help me?
