I am doing dvd to dvd-r. With dvd2avi, I am keeping the ac3, but it is often out of sync. I am multiplexing with bbmpeg, and have come to the conclusion that it has to deal with the audio file. In the output ac3 file from dvd2avi it says there is a delay of 26 ms, or a similar number. I am trying to figure out why this is happenning, and if there is software which I can cut the delay out, ie ac3 editing software. Please help me, I am going nuts!
