wit, your welcome, remember you can choose to use dvd9 as well, see this topic for info on how to switch from dvd5 to dvd9 >
http://www.fileforums.com/showthread.php?t=96925
Then use that info as a guide as to switch this conversion from dvd5 to dvd9 ( its the first volume size that matters, ( how much space the setup files take on DVD, BEFORE starting the conversion, minus the full DVD size ).
IE if setup file was 50mb then for dvd5 4480 - 50 = 4430 OR DVD9 7950 -50 = 7900
DVD5 first volume 4430
DVD9 first volume 7900
Edit ultraARC.ini before starting conversion to the correct numbers if switching to DVD9
as I don't use that size in any of my conversions.
