as of Jan 27th you have new firmware for your new burner, <LITE-ON DVDRW LH-20A1H> Version: LL05, LL06 is available here: LINK Firmware is programming that is inserted into a programmable memory area of your drive, thus becoming a permanent part of a drive. This 'software' is called firmware and can be updated with a firmware flasher. A firmware upgrade can add new functionality to your drive. Also bug fixes and improvements are done by firmware upgrades. It also adds more media codes and write strategies to the drive to improve burning capabilities and disk recognition. slow your burning speed down to 8x or 4x...... just because your car can go 140MPH doesn't mean you should drive it that fast! same goes for DVD writing. Many members say that burning at 16x is ok and I have tried it, too, but it depends on the manufacturer of the disk.... yours is RICOHJPN which is a good second class disk! I would only burn 16x with first class media: MIJs.. Made in Japan disks like: Taiyo Yuden, Sony, Maxell and Fuji.... check the box or spindle label and make sure it's MIJ! or buy Verbatim... made in Taiwan/Singapore and the only NON MIJ disk allowed near my burner! Verbatim is Top Notch! do not multi task or go on the internet and even shut down unnecessary programs .... you're using too much RAM! Minimum requirements of RAM is 512k! I would even shut off your anti virus programs, too, when burning! the stablest version of Nero 7 is 18.104.22.168: Before upgrading to this version I would save my serial #, uninstall Nero, do a registry clean up using this free program, CCleaner, found here: LINK then use Nero7 Clean tool http://ww2.nero.com/nero7/enu/Nero7_CleanTool.html and then reinstall 22.214.171.124 from here http://www.filehippo.com/download_nero_7_premium/ this is a Roxio/Sonic Packet writing software file..... it's been known that Nero and Roxio/Sonic don't mix too well together.... uninstall Roxio/Sonic. some members computers can handle both but when you're having problems uninstall Roxio/Sonic! follow these recommendations and you should have better results. good luck.
