ok, I have an avi file where the framerate is 23.97, which is supposed to be correct for NTSC-film standard. The original file when played on my PC is smooth. I ran it through the NTSC-film template in TMPGEnc Plus, which dumps an MPEG out the other end. Using Nero's VCD template, I burnt this to disk. End result - no audio and the same slightly jerky movement I always seem to get if converting a file, whatever method I follow! Where am I going wrong here then?
