Sony DWD26A OEM crossflashed / Lite-on 1693s ks09

DWD26A OEM crosslfashed and wont burn.
This is a new drive which was origonaly the DWD26A OEM crosslfashed to a Lite-on 1693s KS09.
I have been able to backup a dvd using DVD+RW media but not with DVD+R media.
I am using Maxell 16X DVD+R media and am having no luck.
At this point I am not sure if the drive may be bad.
I have tried many different software applications with the same results.
I would greatly appreciarte any help.
