Help.....Médé....médé !!! Problem to copy DC games !!!

[Toto007 !]

I just received DC new DC gamez but I CAN'T COPY THEM for some reasons !!!! They are all selfbootable, they are copied on a 650 Mb disc but DJ (and many other softwares) asked me to put a blank disk with more space (so I put a 700 mb disc in !) but I get every time errors messages. (I did, in the past, burn DC games successfully but not this time, so I don't considerr me as a newbie...but...)

I tried it with DJ, Sony CD extreme, Clone CD,....but no way ! >>> maybe I don't have the rights settings for copying cd properly .....I hope that someone will help me.....I'm desesperate !!!!!!!!!

Thanks in advance...
