Comandline Parameter for v2isr.exe don't work

Hello,

i have wrote a batchfile which start the recovery gui automatically.

I use the following command in my batch.

V2ISR.exe -ORM -ONVB -RAF

Parameter
-ORM for "Restore MBR"
-ONVB for "No verify before restore"
-RAF for "Reboot after finish"

The Parameter -ORM and -RAF is ok, but the -ONVB do nothing.

"Verify recovery point before recovery" always on. why is this so?

Kind regards
