Hi there! Sorry for my English, I´m from Czech Rep. ->I have an AMD AthlonXP 2600+@2130MHz, 896MB RAM,MSI K6,40 GB Seagate/7200rpm/2MB Cache,Ge-Force 5700, And my LG 4163B write my DVDs so slowly! In the Nero Burning Rom v. 18.104.22.168 it shows Write speed 8X sometimes even 12X(using Verbatims) and the burning process take about 25-28 minutes(full DVD 4,5GB)!!! Alcohol 120 is doing the same! You can burn from HDD or make a copy of existing disc its always the same!:-( But 1-2 months ago it takes less than 15 minutes in both programs. I have already claimed 2 of my previous LG´s (4120B and before it one older) They stopped writing/readind anything! CD/DVD! Can You help me PLEASE!?
