I've been using an LG DVD writer to author my DVD masters at 4x using Nero Burning Rom installed on a Windows 7 computer. After about six years of use, the writer died and I replaced it with a brand new LG writer but the slowest speed Nero is showing me is 8x. I've been using Nero 9 so I went ahead and downloaded the trial version of Nero 2017 and got the same results. I then went out and bought several other writers and found a couple that would go down to 6x; the others only went down to 8x.
So I have a couple of questions...
1. Why isn't Nero letting me burn at 4x? (I've also posted on the Nero forum)
2. Over the years I've always been told to burn DVD masters at 4x to ensure a deeper burn with less errors. Is it OK if I started burning the masters at 6x?
I've been using TMPGEnc Video Mastering Works. The bitrate varies widely depending on program length. The new LG burner will only go down to 6x on both long running DVDs and short DVDs so the bitrate has nothing to do with it. I posted on the Nero forum and someone replied that the burn speed is determined by the firmware of the burner.
Ask yourself a question. If burning a disc at 8x, or 12x, or 16x meant that it would be unreliable....WHY would the manufacturer of the media and burners even offer the higher speeds?? Consumers losing data would be unhappy consumers, right?
I used to burn a lot of DVDs myself (dozens to hundreds per job), had a 1x7 duplication tower. I would try to burn the "master" at 1x to make sure it was "the best", then the copies burned at whatever speed the machine wanted to burn. But guess what I found over the years? All the copies burned at 16x were 100% reliable!! Using top-grade media of course.
So what I'm saying is lose the old-school mentality. If the slowest you can burn is 6x or 8x, so what? Why is that an issue? It's not 2008.
Once I stopped worrying about, my life got a lot better 😉
