Today, I ripped DVD and decoded it to mpeg. When I watched this file size. I was very disappointed. Because, during twenty six hour, I use computer and decoded it. Inspite of that. It's size is three gigabytes. Before I decode. I expect it size will be pressed very well. But source file size is seven point five gigabytes and maked fike is only half size!! It was waste time very much. Umm, yesterday I will chalenge it one more time and change format to DivX.
