Cannot burn DVD

[Niels Weber]

Hi all,

I cannot burn DVD with rawhide, with FC6 all worked fine.
I get the same error, whether burning as root or as user.

:-( unable to open64("/dev/sr0",O_RDONLY): No such file or directory

And the application tells me to enter an empty disk. Nautilus
recognizes that there is a DVD+R inserted.

Is this a known problem? Any solutions?

Thanks,
   Niels
