Dvd won't burn

I have a mx6912 gateway notebook computer which contains a philips sdvd8441 cd/dvd burner. I am able to read/write cds and data discs. My drive is also able to read and play dvd’s. I am not able to burn dvd’s though. I have videos that I have edited down, and no matter what software I use I get the same result. the project appears to go through all of the steps of production, but when the project has completed the cycle the disc comes out blank. I am at my wits end. I attempt to explain the issue, but I believe that they are not fully understanding my issue. Does someone out there have any ideas?

Tried deselecting options like “simulation burn”?
