Description of problem: 
Did a mkbootdisk --iso and went to burn the image.  cdrecord burns it 
without complaint, but the burn always fails to verify, and always at 
the same spot.  Tried several different discs, both -rw and -r, with 
the exact same result. 
 
Switched to the cdrecord-prodvd-2.01a27-i686-pc-linux-gnu binary from 
Schilly's site and the image was then burned and verified 
successfully.  Was using the same readcd to compare every time, while 
is why I suspect it was the burn that failed. 
 
Version-Release number of selected component (if applicable): 
cdrecord-2.01-0.a27.2.i386.rpm 
 
How reproducible: 
always (with this particular image anyway, haven't tried any others 
yet) 
 
Steps to Reproduce: 
1.  grab image I'm using:  
http://kuoi.asui.uidaho.edu/~wes/boot-2.6.5-1.327.iso (made with 
"mkbootdisk --device boot-2.6.5-1.327.iso --iso 2.6.5-1.327") 
2.  burn image...  in my case I do "cdrecord dev=/dev/hdc -dao -v 
boot-2.6.5-1.327.iso" 
3.  attempt to verify the burn... 
 
Actual results: 
[root@ip68-110-7-34 root]# readcd dev=/dev/hdc f=- | cmp 
boot-2.6.5-1.327.iso

etc. until you kill it.  Note the read failure happened at sector 945 
*every* time, regardless of the disc. 
 
Expected results: 
successful read/compare, as happens when I burn the image with 
Schilly's binary.
