Hi, I've been trying to backup a dvd movie into an xvid with ac3 while following this guide - http://www.afterdawn.com/guides/archive/copy_dvd_to_xvid.cfm Everything went well in the guide until i had to multiplex the ac3 with the video. So i got up to the stage of the guide under the heading "Multiplexing the AC3 with the video" where it asks me to goto the "Audio" menu in the menubar. I can see it on the picture in the guide but its not there on my VirtualDubMod. I downloaded VirtualDubMod v188.8.131.52 from the link in the guide (http://www.afterdawn.com/software/video_software/video_tools/virtualdubmod.cfm). Did i download the wrong version or is there a way i can get around this problem? Any help will be appreciated.
