I convert using Tmpgenc to mpeg2 then burn with ulead wrkshp 2. but ulead converts again? the file made by tmpgenc is 4 gig. Ulead will only burn using th 90 minute selection, becasue the 60 is to big(7 gig). if the file to be burned is 4 gig and the dvd is 4.7 gig why would i need to convert or compress. What is Ulead converting? OR what is the best settings to use in Tmpgenc so Ulead won't have to do anything but burn.
