I have just bought the nec 2500a and I am having the following problem
In every disc I write (I have used DVD-r disks -> 4x Samsung,4x Benq,2x Mirror) the burning side seems messed up.I mean that it is not the same colour everywhere.Somewhere in the middle stripes begin to appear and then a thick lifgt coloured stripe exists.Some disks seem to play.Other dont.I use Nero 184.108.40.206 and I have not modified my firmware.
Any clues?(I use 2x speed)
Sorry for my poor English!!
