I find that when dragging videos over to add to dvd burn list on toast titanium 11, that the bar at the bottom is totally inaccurate at measuring when you have reached the maximum allowed space on the new DVD. Frequently it tells me their is ample space on the dvd to burn the listed files. Only after about an hour , I get an error message telling me not enough space on the dvd for the listed selections. So I have wasted a blank DVD and lots of valuable time. Does anyone know how to correct this problem. Thanks, Tomas
