To use 80 minute / 700 mb CD´s:
In version 3.X - 80 minute / 700 mb CDs are not supported.
In version 4.X - As long as the recorder supports writing to 80 minute media ( this should be either in the spec sheet, or can be found from the manufacturer of the drive.) In Easy CD Creator ( 4.02 or higher), at the bottom of the screen, it will say, " estimate based on..." if you click on this, you can choose either 80 or 74 minute CD.
In version 5.X - The time estimate goes to both 74 and 80 minutes, just fill the layout until you reach the appropriate mark.
Direct CD - Will writes to any formated capacity of the disc, there is no specification prohibiting this. Remember that the format takes up room on the disc. ( Approx 75 - 125 mgs on a CDR and about 150-200 mgs on a CDRW.) Direct CD will warn you when you are trying to write more data than the formated capacity of the disc will allow. However, if to much data is written to the disc, Direct CD will not be able to close the disc to ISO or UDF.
