Copy DVD: Device or resource busy
While wanting to use DVD::Rip, Thoggen DVD Ripper and GnomeBaker to copy (or backup) a DVD today, I encountered the strange "Error trying to open: device or resource busy" on my Ubuntu box today.
I solved this by freeing the dvd drive from system access with:
sudo umount /dev/sr0
and everything worked. BTW:
For DVD .iso copies
I recommend GnomeBaker for easy copies...
