when i burn a dvd copy2dvd burns only with speed 2* - but the drives supports 4*.If i use Nero the burn-speed is 4*
Does copy2dvd not support my drive?
As far as I know the burning speed is set by the recorder itself. It has a table of media which it supports. Maybe your DVD is not supported (yet). I have a NEC 1300A myself and I experienced the same with EMTec (former BASF) DVD's. It says 4x at the box but burned only 2x.
On NEC's homepage there is a medialist . Check it out
Now I use Verbatim DVD+R DVD's with no problems
Have you tried to change the burning speed, which you can change via options, tab "Writing devices" in CopyToDVD. Here you can select Max, 2-speed or 4-speed.Change it to 4-speed and try again burning a DVD.
