I am using smartripper to create M2V and AC3 files. I am pulling these into dvd wise and multiplexing them into a vob file which as far as I can tell is the only file format dvd wise will import. However, the vob file dvd wise creates from the multiplexing process has a horrible lag between the sound and the picture and the picture is very choppy. I have tried to use smartripper to rip into a vob file but dvd wise will not accept it. Is there any workaroud to this problem or am I doing something wrong? I want to keep a dvd quality picture and also 5.1 dolby sound. I am so close to creating my fist DVD...PLEASE HELP!!!
