i want to convert a video file from [vob] format to another format such that it has the same picture quality but half the size which can me burn 4 different movies in a single 8GB DVD
The only possible solution is convert using divx codec. Download virtual dub and K-lte codec pack full. install both of them and use divx codec to convert.
Use softies like DVD shrink. It could make a DVD9 at the size of normal DVD with all the menus nd xtras with very little sacrfice of quality which u won't even notice.
Yeah , you can use DVD shrink. If you reduce the file size too much there will be
noticable loss of picture quality!!
