Major problem while burning

[Impo]

Hi everyone,
Today I bought two different brand of DVD-R, Emtec and B.O.S.
Maybe you don't know them but several days ago I burned on B.O.S. without any problem.

Today, I did the same thing I ever did with Nero 6 and it's impossible to record.

I always have the message "Illegal Disc" and "Could not perform start of disc-at-once"

I really can't understand, everything was fine with my older DVD today I bought new ones and they don't work.

I buckuped the original DVDs with DVD Shrink as ever

I have a DVD-R/RW NEC 1300A recoder.

Does anyone can help !!!!!!!
Is there a protection on the new DVDs???

I saw that someone posted for a similar problem but noone gave him a solution cause he wasn't specific enough. Hope there is enough information on my post.

Thank you everyone

I don't know B.O.S. but I know Princo. Some reviewers on the DVDR help site say their NEC1300 works ok with them. I buy a drum of them and zilch. Maybe just a bad batch.
I don't know Nero well as it fails to recognise my writer (bundled with an earlier CDWriter) but have you checked for upgrade? V6 is buggy by all accounts.

Version 6 Nero is seriously flawed. I would recommend upgrade as Sfheath specified also
