This is what happend to me. I bought my Lite-On 811s 3 months ago. I always use Princo DVD-r. I have been burning iso's, dvd backups with no problems. But after 1 month my first failed dvd was a fact.
If i want to burn for example a compilation with a few divx and mp3, and the burning starts i can see that my RAM memory (in taskmanager) gets drained till 0MB, then the RAM shoots up to ~40-60MB en gets drained again.
I brought my DVDRW back to the store, they tested it and said there's no problem.
I found out later, when i disable my norton antivirus, the memory is not getting drained But still i have 1of5 dvd-r's failed. Odd enough this never happens when i burn DVD-VIDEO, from image or just burning VOB's. I've tried closing all apps but still f*ck ups. My IDE config is ok, first channel: 120GB&80GB WD disks, second channel: 811s master, 16x DVDROM slave.
I really dont know what to do anymore, can some1 maybe help? Maybe u can tell me wich firmware is the best for princo dvd-r. Cuz this cost me a lot of money.
I use Nero 188.8.131.52 and alcohol 120%.
