No ... It does not work.... at least like this.

To check this I first used  disc1 which is sha1sum & media check OK. (on the same comp on the same cdrom). 

# dd if=/dev/cdrom | sha1sum
dd: reading `/dev/cdrom': Input/output error
1342144+0 records in
1342144+0 records out

(Oh CD is mounted...)

# umount /media/cdrecorder
# dd if=/dev/cdrom | sha1sum
dd: reading `/dev/cdrom': Input/output error
1342096+0 records in
1342096+0 records out

So it still doesnot work 

correct SHA1SUM is
43546c0e0d1fc64b6b80fe1fa99fb6509af5c0a0  
FC-5-i386-disc1.iso


Therefore I did not bother to check other OK/failed discs.
