cdrecord -speed=4 -sao --dev=ATA:1,0,0  $1

I've also tried -dao and the default which is -tao. I'm getting the

Run it as root. There are problems with cdrecord and the new scsi drivers
in the newer kernels. Whose fault it is ai do not know (Schilling shouts
loudly that it is the kernel people)

I'm having trouble burning an ISO to a DVD. I've burned CDROMs on this
drive previously but never a DVD. I've tried to do the burn with -tao,
-dao and -sao switches. -tao isn't supported with -dao an -sao it
indicates that the tried to burn it but I'm unable to mount the result.
