I downloaded a divx file which has two audio tracks according to avicodec. One is the original soundtrack (I assume) and the other is a commentary. When I play it in wmp, it defaults to the commentary and extracting the wav file with vdub also only produces the commentary track, but what I want is the ost so I can encode and burn as a SVCD. Any ideas how I can extract the ost and do away with the commentary?
