After converting and burning many movies without any problems, I have run into something new. I am trying to convert a dvd rip (downloaded from net) to svcd. I scanned for errors in vdub--none, I extracted audio and saved as wav. I watched whole movie on puter and works excellent. I load everything into tmpgenc and begin encoding. I always make clips and check for audio synch before doing whole movie. Tmpg windows shows movie converting, after 1 min clip I stop to check. playback is fine until a certain part of the movie and then I just get black screen and no audio. Why? and can I fix it
