I have recently tried burning slayers to a dvd instead of a cd-rw and for some odd reason its not giving me the option to burn it to a dvd using Nero 6 SmartStart.. any ideas on what could of caused this.

use discjuggler
burn cd and dvd images
pick file
under advanced choose
mode1/dvd -diff version may change
block 2448
offset 0
toc cd-rom/dvd
then burn

Thanks
