The software isn't the problem, because i write many DVD on LG4081b with it. But now i change for model lg 4082b and i can write cd and i write 1 DVD-R before the problem happens.

My system is winXP Pro.

I can still read/play DVD and cd.

The DVD writer is for the format i want to write DVD-R.

I try to write cd and that works perfectly, so the problem is to write DVD.
