Help please, Sector 0 is empty

I am a newbie in the world of DVD authoring and I am trying to set up my writer and software properly.

I have troubleshooted and troubleshooted, simulating my athored DVD works perfectly, but after burning it, upon trying to verify the DVD I get a response that “Unreadable sector 0 is empty”

I use DVD setting in Roxio Toast v 5.1.1, where my VIDEO_TS and AUDIO_TS folders have been placed in the default: untitiled dvd main folder.

The footage has been assembeled in Apple DVD Studio 1.5 using OSX.
I have so far wasted 8 dvds now, and any suggestions will be deeply appreciated.

problem solved!

reason was bad media of the type “eProFormance”, I tried two variations (12 disks in all)

after testing LaCie, Pioneer and Primedisk media, and all of them were written succesfully, the solution seems obvious: to avoid the “eProFormance” DVDs in the future.
