I have a few divx files that have ac3 and I want to keep the ac3 when I convert to dvd. The ac3 files are already 48000hz so I don't have to change it or anything right ? cause it's 48000 and not 44100hz. anyway I saved the file under direct stream copy with vdub.,then converted the video only to dvd but it has a framefrate of 23.97. I heard you can mux ac3 to m2v with tmpgenc but it says illegal mpeg stream when I try, any ideas? I have besweet,ulead dvd movie factory 2,newest version of tmpgenc plus, vdub mod and everything.
