"Insert an empty medium"

I have burn several dvds with nero express. The last days I do the usuall steps but the message “Please insert an empty medium” appears when I press BURN. In the beginning I thought that the empty dvd disk was damaged but unfortunately it does the same with all empty dvds I tried.
Please help.

That error message will comeup when the complentation or ISO that you are tring to burn is too large for the medium that you put in there. Make sure that what you are burning is not “in the red” on the size meter or beyond the max capacity of the media. You can put a blank disc in the drive and use Nero’s disc info option and see if it reads it as a blank disc. This will help you determine if it is the media not being read.
