slow ISO reads

[sodub]

when I tried to copy a DVD Clone CD took about two hours to read the ISO, then 15mins to burn it. I later tried to backup a game CD and after 20 minutes the ISo read was only on 1% so I cancelled it.

Is it normal to take this long? When I used Nero I could copy a DVD in 10 minutes. My Asus disc drive is new and works fine with Vista.

Help would be appreciated
