Troubling DVD Writer

[davinci]

I am facing a peculiar problem. I hav recently bought a Sony DVD RW AW-G170A. It can write DVD without any problem. But now i hav 2 DVDs which was written by this drive but the drive cannot read the dvds. But it can read all other dvds without a problem.Then one day suddenly i discovered that my Samsung DVD-ROM SD616Q can read those two dvds without a problem.Can any one tell me how to fix the problem

^^^This can hpn coz of outd8d drivers... Sometimes d Digit DL_DVDs failed to read on d new Lite-on DVD burners... Updated drivers resolved d issue..

Chk the sites fer newer drivers if released...

G170A mus be rel8vly new...
