for beginning you need to download ImgBurn 2.3.2.0 exactly this version, because since other can't setup user Layer Break!!!!
1) Install and start program.
2) go "Tools" -> "Settings..." -> bookmark "Write" and adjust in accordance with picture:

3) Then "File" -> "Browse for a file..." -> choose your ".dvd" and write image on 2x or 4x speed
4) if at the end program show ERROR just click CANCEL and wait while track is closed!!!
That way i burn 10 DVD-R DL and all works GREAT! but i'am not sure about backup games from it!
