How do I find whatever it is that wodim or readom thinks is using /dev/sr0 and kill it?
So far, reboot is the only solution I've found that works. I don't like it. I want to be able to use my DVD-burner more than once without rebooting. lsof has not helped.
umount will get rid of the resource busy error, but then I get [hennebry@localhost data]$ readom -clone -f dvd.clone dev=/dev/sr0 Read speed: 22160 kB/s (CD 125x, DVD 16x).

I'm trying to clone a dvd I made on a standalone dvd recorder. I had managed to make an iso file from it, but the resulting dvd would not play on the recorder, so now I'm trying readom. The iso file mounts, but pointing vlc at it does not work.
