Description of problem:
DVD writer need iso-files with a multiple of 32kb,
if this is not true, the controller will pad to 32kb.

That means, if you burn with growisofs the DVD image of
fedora, the size will be changed to  2466410496+4096 bytes.

So if you try to make an md5sum on /dev/dvd you will get a 
different md5sum.

Please ensure, that DVD images in future will be a multple 
of 32 kbytes.

Same problem exists for x86_64, 
here the size will be changed to 2639267840 + 15*2048 bytes.


Take care,

Winfrid
