The mediacheck program does not work reliably since the 2.6 kernel was 
introduced. You might try to pass linux ide=nodma in order to use the 
mdiacheck program with better results. The issue has to do with either 
additional padding needs applied to the discs burned to overcome the 
error, ide=nodma needs passed.

Anyway, do not be too concerned with the results from mediacheck if the 
sha1sum is alright. I went through a set of discs myself back during the 
switch to the 2.6 kernel.
