[tango_cash]

i have a sony dvd writer .
and today i burned a dvd at 8x and checked on verify disc after burning(i always do that).
the burning process got over succesfully but during the data verification process it gave "data verification error".
i have been burning dvd in past but didn't have this problem.this is first time.
how do i make sure the disc has been properly burnt???
