copying already burned dc games?

Sounds to me like you may be be using 74min media where you need 80min media. When you put in the original disc there will be some text uner the source window in discjugggler. This will show the length of the image you are burning si if the image is greater than 73.59.59 you will need 80min media. another thing you could try is (assuming you haver made sure the originals work) is the use the same length media as the originals.
