mkfs.ext2 /dev/sr0
which took a while!
Then mounted it with:
sudo mount /dev/sr0 /home/me/tmp/dvdram -o rw
Unmounted with:
sudo umount /home/me/tmp/dvdram
After re-inserting the disk I get dmesg errors:

Oops! Looks like I should have formatted as UDF.
I had installed some udf tools with:
sudo apt-get install udftools libudf libudf0 libudf-dev
Looks like they are now picking up the DVD-RAM disc automatically and I maybe shouldn’t have formatted as ext2. So tomorrow night I will crack open another DVD-RAM disk and see where that takes me.
