Dvd copy with moviejack 3 ( 3.09.304)

hello,
i’v just bought Moviejack 3 latest version.
operating system is XP. I’ve got a samsung cd rw and a Philips DVDRW416
when I’m try to “Backup a DVD” I choose only the main program because my rw dvd is 4,7 GB…
After ripping it tells me the process is completed and it didn’t burn it to the dvd?
Can somebody tell me what I did wrong?
Thanks…
