I am using roxio 9 to encode and authormy movie duration 3h.14m hours long which as a 775MB divx file and in spite of my many attempts it just won't fit to disc on my 4.7 DVD-R. I use roxio as it converts immediately. What can I do to overcome this problem. I even joined 2 divx clips which became 1.62GB yesterday and they burned to disc directly with no problem. Where might I be going wrong with this. Could it be that roxio doesn't like the movie or something? Any suggestions?
