Problems with iomega dvdrw4216ind-a please help

the only brand of dvd-r I can get to burn is tdk, even tried imation. nothing else works, anyone have any ideas? p-lease help, thank you. I am also using nero.

Post more info, eg. a logfile.

it is real plane and simple, i put in any other dvdr besides tdk and it comes up as no disk found, double click on the drive, and it is like there is nothing in that drive doies not recognise anything but tdk.
Please help, thank you.

Then clean the drive first.
