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 these ISO images burned to CDs:- Had problems with the media check failing on disks 2, 3 and 4 of Fedora Core 3. Using the command cdrecord -v speed=2 -eject dev=0,0,0 -pad <image filename> -pad got the media check to pass on disks 2 and 4 but disk 3 still failed The command 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 work. At the end of writing disk 3 cdrecord reported 100k of pad data added to the CD. Hope this helps somebody. It might be best for everybody to use CD-RWs in future, to cut the production of drinks coasters.
