Would like to know if there is a procedure or program that I can use with DVDShrink that will allow me to inset, inject, add,etc information into a DVD disc that is not full. I have three DVD+R which only have about four to six minutes of information in them. I have not been able to add any further information to them. Are these disc(s)coasters, or are they still usable. Any help is greatly appreciated. cowpoke
