This is just a hint for you. /dev/sr1 is a read-only device per definition.

You can't enable things which are not there. A read-only device will stay 
read-only no matter what you put in fstab.

That clearly depends on the filesystem you use. If you use iso9660, you have 
to create an image which is burnt to the disc unmounted.

However, if you use UDF on RW media (CD or DVD), you create a device mapping 
via pktcdvd.ko and pktsetup and mount the disc just like anything else.
