Here in Brazil the LG4040b is about U$ 220,00. Until now I just tried to burn at 2x because I have a slow Pentium III 600, with a 7200rpm Maxtor Hard Disk (running at DMA-66 in a ASUS P3W) under Windows XP. I have tried Nero 6 (with latest updates) and I had many read errors under PowerDVD, however the discs could play right on Windows Media Player, WinDVD and many standalone DVD Players. I tried RecordNow Max but it doesnt reconize the LG4040b unit. So I tried "burnatonce" and I got a strange error during burning stage. So I have decided to use the Recorder Gold5 that came with my LG4040b. I learned how to burn DVD-VIDEO with it at http://www.super-klaus.de/BRG_e.htm The discs I burned with this Recorder Gold5 played without any trouble in PowerDVD. I think Nero6 still have some problem with LG4040b. I just found and tested Princo4x and another cheap media with a "-A-" on the center of the disc. I burned about 15 discs without any problem. For my surprise even discs with risks under surface were able to burn and read (maybe I am a lucky guy . My LG4040b came with A104 firmware and I didnt try the upgrade to A301 yet. All programs I tried really reconized Princo as 2x. My doubt is if I will be able to burn at 4x on my old Pentium III. Does somebody burn at 4x using a slow machine like mine? I would like to known which machines (at least Processor and Clock Speed) users here are using to burn at 4x with LG4040b.
