I was trying to convert an mkv file so that I could burn it to a dvd, and I found a guide showing how to do it, but when I select the video I want to convert it says error divide by zero and another error. The program I used was Avi2dvd, and the guide can be found here : http://www.afterdawn.com/guides/archive/convert_mkv_to_dvd_with_freeware.cfm edit: I tried installing the Xvid codecs too, still doesn't work.
