problems with k3b burning iso
 

i have an ISO of a dvd.

when i burn this iso, all "seems" go ok, but k3b write less mb of the iso total (for example the iso is 3548 mb but k3b writes only 3540)

the burning seems ok, but after when k3b do the verify check comparing the iso and the dvd burned it gives me error!

of course! because it writes less mb, but why it writes less mb (this is the question, like someone wrotes before) ?

help pleae, i have no hint about this werd problem :confused:
