Can you Burn an already burned game by......
 

placing the game in my dvd drive.... and the cdr in the burner? using CreateCd or DJ3?...aiight drop ya two cents.. thanx peace UNo!

Not likely. It might work, but the best and most reliable way is to place the copy in your CDRW and make an image file. Then place your blank in the CDRW drive and burn the image to the blank.

I'll second that. Make the image file first, then burn from the image file.

The problem with a disc-to-disc burn is that they have to be fairly synchronized with both the reading and burning process. There's far less room for error when copying discs for DC games as opposed to making a music cd or the like. If your dvd drive reads the backup copy any slower than the burner is writing - at any point during the copy process - it's going to produce an error.

Bottom line, it's always worth the extra time to make an image file first (which doesn't take that long, anyway).
