burning CD-R's

[René L. Reingard]

hello

i downloaded the Live-CD of Hoary (hoary-live-i386.iso)
tried to burn it in Nautilus to an empty CD-R.
the CD-Drive in my laptop is a CD-RW/DVD-ROM Drive (HAL talks about: QSI  
CD-RW/DVD-ROM SBW-081).
after pushing "burn CD" another window comes up with the question where to  
save that file. options are: putting the iso-File to the desktop, personal  
folder or the filesystem. and that's all !! looks so silly :-(

the drive got autodetected by Ubuntu Warty as CD-ROM1 (the icon) and the  
line for it in /etc/fstab looks as follows:

/dev/hdc        /media/cdrom0   udf,iso9660 ro,user,noauto  0       0


if i push on the icon of the CD-Drive, while a CD-R is inside, the error  
message is:

mount: wrong fs type, bad option, bad superblock on /dev/hdc, or too many  
mounted file systems


i once also tried to change "ro" to "rw", but then the icon changes  
automatically to a harddrive's icon and the error is:

mount: block device /dev/hdc is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/hdc, or too many  
mounted file systems


NOW, how to deal with that friends? what to change, what to set  
differently?

regards,
René
