I have 2 DVD burners on my Gateway computer, with Xp as my operating system. Sometimes my burners run extremely slow...Like 075, while normally when I first start burning for the day my burning speed average is around 6.2 using 8x media. Does anyone have any ideas on what my problem could be. I have a pentium 4 with 1.8 ghs and 768 rambus memory. Burners are Sony 510A whichs is surposed to burn at 4x and a Samsung 16x dual layer. I am using 8x Ritek DVD-r media
