@mmyof3 U should be able to do this with any of the DVD writing programs like WinDVD Creater and DVD Producer and Record Now X these are some that i know of and there are more out there... These should do the job fine cause your just backing up a DVD ROM disc...
Try using AnyDVD or DVD43 in the background maybe it has some protection those can pick up try it out and c if it works with nero...
hi games have major copy protection worse than dvd films have, 2 major contenders are SAFEDISC and SECUROM, alcohol 120% is a kickbutt app for this sort of thing it has settings to rip and burn for each, as these protections are updated regularly... try the cdr forum as games are talked of there, mention game name too it helps, so people can guide you!!!
