I used to be able to convert my asf. files to mpg but i think i deleted something becasue i can no longer do it. I can't convert any asf file now, it says they are all unsupported. I downloaded all the codec's, Nimo Codec Pack, even the divx codec's 3, 4 +5, and even a MPEG2 codec, SMR patch. Simply...

What codecs do i need to convert asf to mpg?
