growisofs blocked by remount

[Olaf Mueller]

Hello,

till yesterday I could burn dvds  on fc5 without a problem. But Since
today, the following error message appears on trying to burn a dvd.

$ growisofs -dvd-compat -Z /dev/dvd=dvd_image.iso
Executing 'builtin_dd if=dvd_image.iso of=/dev/dvd obs=32k seek=0'
:-( unable to O_EXCL /dev/dvd: someone was in time to remount?

Who or what blocked here growisofs by remount?
I have disabled haldaemon and also autofs but the error still remains.

How can I prevent services in fc5 from getting access of my dvd-player
by auto?
Thank you!


regards
Olaf
