Nero Cd-DVD Speed Problem

After burning a dvd with nero, i wanted to scan it with cd-dvd speed, now the cd-tray was still out while i opened “cd-dvd speed”, when i closed the tray i got the message that the dvd was empty. after closing cd-dvd speed and opening and closing the tray the dvd was recognized normaly.

Is that some error in Cd-Dvd Speed or so ?

Anyone else had that ?
