I now have four install CDs each passing the media check. They are made using
the same CD-RWs that were failing last night, so I don't think the media
manufacturer is of any significance.
In case they are of use to other Fedora users, here are my notes on getting

cdrecord -v speed=2 -eject dev=0,0,0 -pad padsize=50s <image filename> -pad
then got it to work with disk 3.
The -pad in the final command might be superfluous but the command seems to
