I spent all the morning doing test with different medias (DVD-R, DVD+R, DVD-RW) of different brands (Verbatim, Tdk, Fortis, HP, etc). To my disappointemt, I managed to get good burnings only using DVD-RW medias (see picture).
Using DVD-R or DVD+R I got terrible burning (1x speed, high CPU usage, low buffer)
I tried to reset the learn media, but the situation did not improve...
Do you agree that it is a very strange situation? Working well with DVD-RW medias, and working bad with DVD-R or DVD+R....
What can I do else? What about the "Reset HyperTurning" option? Can it be of any use? Any other suggestion?
PS: Now that I remember, if I recall well, the problem began after I did a burning with a DVD authoring software, DVD-lab pro. The software has an in-built engine to burn DVD. I used it only once and the burning was very bad (very slow, high CPU usage)... after this, the writer began to work in the weird way it's now.
On an warning pop up that the software popped up before the burning there read: "The included Record module uses a general ASPI interface. It may not always work for every recorder and media types. It is recommendend that you use for final burning the software supplied with your recorder"
May this have messed in some way my recorder?
