I ran into this the first time that I burned a DVD image of Libranet's new, 
3.0 release. Growisofs output indicated a successful burn, but the new image 
failed the md5sum test. I finally noticed that the dvd image was several 
kilobytes larger than the original image. Eventually, using dd & od I 
determined that the difference appeared to consist of several blocks of 
binary zeros appended to the end of the original image. As a test of this 
theory, I used dd to truncate the extra blocks and the resulting image passed 
the md5sum test.

Cheers!
