dvd burner

[John]

  I tried a couple of different dvd burners on a FC6 box; the two 
programs I've tried (Brasero and GnomeBaker) keep telling my there's no 
blank dvd in the tray (there is). When that happens, the tray kicks 
open, which I close. The disk is accepted and I'm able to select the 
files I want to burn, though once I hit burn, I get errors. With 
Brasero, the errors seems to be with the program.    ?????
