Disk content error?



I use Nero Vision Express 2, i create my project add the chapters the menu ect. I’m happy with it and i click next all the way to burn.

About 15 to 17 minutes into the burn it pops up and says: Unable to burn, can not read disk content.

what does this mean!? I was using a memorex dvd and then i tried with a Verbatim disk just incase. Both times its said the same thing.

I could just use burning rom instead probally but i want the chapters and menu and not sure if i can do those with that program. I’m a newbie =)

If anyone has any suggestions please help me =)
