Help.....Dvd Data copy error

Hi,i make a dvd data burn inside a media 1 weeks ago.
now i want to copy to my friends pc.
but some error came out,i don’t know what’s wrong
but i did check with VSO Inspector and find out some error on certain file.

anyway i can’t fix it,one of the file is ISO file.

i think i make a mistake that when i burn the data i escape the verify process due to safe time.
is it nesscessary to verify all the file after we burn ?

how to overcome this problem,anyone pls help ?

Only real way to overcome this problem is to get another version of that file.
Verify function is just for that, skipping it might cause problems. And here it did…
