Sony dru-500a

[TATTY]

Hi
Recently bought the above drive and have made a backup .img file of my Starwars attack of clones using smartripper, remped and spruceup.
I've been told to use prassi primidvd but it doesn't recognise my sony rw.
Nero doesn't do .img files either.
Can anyone tell me which software i need which supports my sony.
This would be a great help as i don't want the kids to ruin my original in the downstairs dvd player

Please help.
