disk size too small in nero
 

im having trouble burning games over 700mb in nero. i used cd2nero to get them to be .iso and i know it can be done but it will not let me do it. is there something im missing? please any help would be greatly appreciated

look in settings there's an option to allow nero to use bigger cds, if it doesn't try to update to lattest version, I really don't recomend you nero to copy games, try with cdclone it is much better.
