I also have the same LG drive on SuSE 9.2.
MC is right about using mount, but I use:
mount /dev/dvdram /mnt
Normally, you have to be root to do this on SuSE. I'm trying to find an easy way to enable it under submount, so any suggestions would be very welcome! I did chown neil /mnt to enable normal read/write. No formatting was needed on my PC, it just worked.
One thing to be aware of is that the drive buffers writes until it's actually necessary to write to disk. In the case of my PC (with 3GB physical RAM) this can mean that unmounting can take a loooong time!
